Dunlop  Grandtrek ST30

I dont think this tire is as monstrously terrible as some revies claim.. From my experience, Ive driven 45k+ on these, and I believe I can still get 10-15k more. Earlier on traction was better, but now theyre crap, especially on wet roads. I cant even go up a medium incline from a stop if the surface is wet. Im super cautious when conditions are wet-- no confidence whatsoever. Dry tractions not terrible, although its relatively easy to get wheel spin in 2nd gear. Turning and responsiveness on dry isnt bad. Im not afraid to take a corner at higher-than-normal speeds. I would NOT purchase these tires if I had the choice. Much better options available for the same $83-$100 range. Looking to purchase BFG Traction T/A H or Bridgestone Potenza RE750 in the future.

This is OEM tire on my 05 Civic. It's more sporty than I expected with quick response in mu daily drive. Never have any problem or hydroplaning on this set. This set has 50000 miles on them and they still have 5/32 left. I typically replace them at 3/32, soot may have another 8000 left. Some of the reviews here have too high an expection on it. It depends on driving styles and good rotation more than anything else. For OE tire, they are better than continental touring contact I have before. Will probably buy another set if on sale.

Yes these tires are expensive and I would not purchase them again because of the price. Despite the bad reviews these tires are not horrible. The Negative reviews are mostly based on perceived performance expectations based on correlation to the price of these tires, these tires are expensive because they are mostly fitted as OEM tires. Bridgestone like many other companies who supply OEM tires to auto manufacturers know that there are some people out there who will shell out the dough for whatever model of tire was OEM on their vehicle. While the segment of the of the market that choses to get whatever model tires was on their car when new may be small it is still lucrative. The price of these tires is all marketing and nothing else.

Disregarding the price point and in an unbiased opinion based solely on performance I find these Bridgestone Potenzas to be above average in every regard except for wet traction. Tread Life was pretty good for a low profile 160 rated tire, I got 32,000 miles and could have made them last another 3-4k if I wanted to push it. Tread wear was relatively even except for the outermost block of tread which was well into the wear bars overall thought the tires had on average 3/32 left. Noise level was was almost silent for the first 15-20k miles and even at 32k miles was acceptable. Dry traction is very impressive as well as Cornering. Steering performance was acceptable as well as Ride Comport. Wet traction is the achilles heel for these tires as even when new the wet traction left much to be desired for and when I replace them at 32K because they got kinda scary at that point. I can't comment on Snow or ice since I live in Hawaii. I replaced the Bridgestones with Michellin Piolt Exaltos PE2s and will give a review of the Michellins shortly.

I have done some crazy driving with these OEM tires on my Prelude. If they can keep up with all of the hard cornering I do and the hard acceleration and braking, then they cant be that bad at least on dry pavement, but they do leave a lot to be desired when it comes to wet grip. I definitely would not recommend buying them. They are just not a high performance tire. They have however put up with a lot of punishment from me, but there are much better choices out there for a replacement when these wear out.

Awful, awful, awful in the rain. There was barely any rain on the ground (on the fastest intermittent settings for my wipers) and I hydroplaned on these tires through a red light today. I was only going 35-40mph when I started braking. I braked moderately hard, but nothing that should have thrown it out of control like that.



Simply amazing how awful these are in the rain for an "All-Season" tire. Please save lives by buying something else.



Handles fine in dry conditions, however.

These were the OEMs on my Subaru. They were alright in the beginning, but they had a severe tendency to squeal on turns. Approaching 30k, they began to exhibit a frightening tendency to skid on wet roads. I felt compelled to write about this tire since last friday I almost drifted into the side of the 280 freeway in foggy weather that could have resulted in some serious damage. This is a all-wheel drive vehicle and to lose control says something about the tires. The treadlife on the RE92 are nothing to write home about either. At 33k, I am very close to the wearline and I consider myself an average driver. You should definitely get rid of these before 30k.

These tires came stock on my Civic. They ----. Don't buy them, there are far better options for less money. My biggest gripes with these tires are the wet traction. These would spin out all the time in wet weather. Starting on a hill was very tricky due to the poor traction. That made me feel uncomfortable with turns and bends in wet weather as well, so I'd take turns slower than I would with other tires.
As for cold weather. These tires were horrible in the snow, slush and ice. The rubber got really hard and even in cold/dry weather the tires performed poorly.

As for warm dry weather...they are ok. No real complaints. Not too noisy, not too hard. Average.

Overall, they are poor in the wet, cold, snow and slush. For other conditions they are average. There are better tires available for less money.

Tires came stock on my 2004 WRX. Ive noticed them on many other stock cars, like Mazda Proteges. Bottom line is these tires are total crap. Wet traction is horrific to say the best. Downhill wet stops require heavy use of ABS. If this car wasnt such a performer, Id be sliding off the road all the time. Snow traction is horrible as well. Id go so far to say they are a safety hazard in bad conditions. Dont buy these tires unless they are very, very close to free.

These tires came on my car when I bought them. Dry roads they are pretty awesome, but if theres any moisture on the road forget about it! My old car, with bald tires (and I do mean bald) handled better than these. Theres a turn by my house where in my old car in the rain I could take the turn at 45-50 and be fine. Now, I cant go around that same turn even at 35 without sliding adn feeling like the car is going to lose control. I drove in the snow (light snow) with them ONCE... never will again. If you enjoy anxiety attacks while driving and fearing for your life, its a great tire in wet/snowy/icy conditions. Id replace them right now if money wasnt so tight. I still have a ton of tread left, probably 75%, and that seems to be the only redeeming quality of these tires.



So I suppose in summary, Im sure theyre excellent tires if you happen to live in an area that doesnt get a ton of rain, or where it doesnt snow or get icy at all. But my recommendation is to NOT... NOT purchase these tires if you value your life and those around you, and live in an area where it snows, gets icy, and rains a lot.

This tire are good, not great, for the first 10k miles. After that, wet traction is really poor and brake the car in a wet down-hill road can be a real problem if you need to make it fast. The tires has now 30k miles and I have to change them without any delay. They are also very hard and poor confortable. Based on the reviews I have read in this site I am going to try the Potenza RE950. Hope I have better experience or it will be my last Brigstone tires. Resuming: I do not recomend Potenza R92 tires to any one.

Dont ever buy these tires at retail price. The sidewalls roll way too much unless you inflate the tires to at least 40 psi. After half the tread is gone, they are totally unsafe in the snow, and rain performance starts to decrease significantly too. My 195/70 14 winter tires performed just as well as the RE92s when inflated to manufacturers specs.

This is a tire that is "Ok" but personally I know for a fact I will never buy them again... I guess, when I think of a tire that is almost 200 dollars, I think it should be a "top notch" tire, and this is not near it. Nothing about this tire stands out to me! The wet traction is not very good, and dry traction is so-so... I have some suspension mods done on my Scion tC, and I havnt had any other tires on the car, but it handles pretty nicely... None the less, wet traction, u just are not sure what is going on beneath you... I only have about 11,000 miles on the tires, and I dont know how they are wearing... I know I take corners way too quick, so no tire is going to wear very good for me, but I will update later on when I replace the tires, or see noticeable wear... I will give Scion a A+ though, for putting 169 dollar tires on a 17,315 dollar car! Thats pretty nice if u ask me, its just too bad they didnt put like BFGoodrich G-Force Sports or something like that! I would look elsewhere personally for a good tire, but its up to you! I would give these a 7 out of 10 (low seven)...

Worst tire Ive ever owned. I rotate and care for tires (and vehicle) religiously and yet these tires are absolutely BALD at 25,000 miles! They would have been considered too worn at about 17,000 miles! Absolutely ridiculous! Never again, Bridgstone!

These were the original OE tires on my wifes 2000 Subaru Legacy L Wagon. To say her driving style is "easy going" is an understatement. All four tires were completely cooked at 23,000, despite scheduled rotations and alignments. At 23,000 each tire wall was cracked between the sidewall and the tread, and the tread was down to 5/32. Maybe we did something wrong.... I dont know. Wouldnt put another set of these tires on her car if they were given to me. Switched to Firestone LH30s for less money. They came highly recommended by several independent dealers and have high ratings on Tire Rack.
