Dunlop Grandtrek ST30 Tire Review & Rating
The Dunlop Grandtrek ST30 all-season highway tire is specially designed as original equipment on vehicles like the Toyota RAV4, Highlander and several other light trucks and SUV’s. Dunlop features this tire as being very versatile in a wide variety of weather and road conditions.
Dunlop uses an all-season tread compound and asymmetric tread pattern that is M+S rated to help in delivering enhanced control, comfort and safety whether on city streets or out on the highway.
Four circumferential grooves aid in expelling water from the tread and increase grip on wet roads. Unfortunately, this is not a strength for this tire, which is what we’ve heard from several drivers in reviews. The asymmetric pattern creates better handling and performance on various types of terrain and in various types of weather with increased braking ability.
Multi-Pitch Tread Design Technology is used to reduce road noise and provide for a more comfortable ride, but again, this is not an area that this tire excels in.
Dunlop Grandtrek ST30 tires are available in 17-18 inch sizes and sport an H-speed rating. A limited tread warranty is included as well.
Pros
- Dry and wet traction is very good on most surfaces
- Solid handling on dry pavement
- Comfortable ride
Cons
- Not the best on wet roads
- Winter performance is lacking
- Road noise increases as tire wears
- No mileage warranty
Overall Thoughts
The ST30 provides a mixed bag of results when it comes to performance, comfort and treadlife. On the plus side is this tire’s dry handling and traction. You can expect quicker steering response and good on-center feel. The ride is comfortable with the exception of potholes and other rough surfaces, but that’s the case with most basic all-season tires.
On the other hand, this tire has a number of areas that could be improved upon. The most glaring would be its poor traction and braking on wet, snow or ice pavement. It falls woefully short of other models like the Michelin Defender LTX M/S or Cooper HTP among others.
In addition, road noise becomes much more pronounced as the tire begins wearing. This is also a big issue for many drivers in their reviews on this tire as well.
Overall, the ST30 is best suited as O.E. and even then we feel you could do better. Based on its performance and higher cost over other top tires in this class, we can’t recommend this model. As mentioned above, tires like the Michelin Defender LTX M/S, General Grabber HTS60, Cooper Discoverer HTP would make for a better option in our opinion.

I believe these were original on my used 2013 RAV4. I’m at 75k. Like other reviewers here are saying, my tires are “dangerously dry rotted” according to my Toyota dealership. The treads are showing expected wear levels. No complaints concerning performance over the years.
These came on my 2018 RAV4, and by 20k miles they were handling very poor in snow. It was so bad by 25k that I’m pretty sure my old PT Cruiser had better snow traction with the cheapest tires I could find. I just replaced them at 35k before winter comes again, and they were pretty badly dry rotted despite being only 3 years old. They were also terrible in rain towards the end. I would start hydroplaning at around 55mph in mild rain, and driving in heavier rain was downright terrifying.
And yes, I rotated them every 5000 miles.
I have a 2014 Toyota Rav4 only 25,000 miles still have great tread but all four tires are showing signs of dry rotting between the treads. Changed all four due to future road trips.
Everyone on here made all these reviews up! I have a 2014 Toyota rav4 with 46k on it now and no tire noise, no steel belts showing, handles good in rain and snow!!! Tires still not at the wear bars!! Just dry rotted. Hows that working out for you?!?!

Got nail in passages rear tire. Took to sams for a patch. Told tire can not repaired because of a inner foam belt that runs down the center of the tire. Approximately 500 miles with nail in center of tire. These tires came standard on newly purchased Nissan Rogue sv (2019).. Very upset having asked dealer if the tires on this SUV were run flat’s and if they could be patched. Told were not run run flat’s and could be patched just like any other non run flat tire.
Hi Kenneth, sorry to hear about this. I suggest you contact Dunlop through their email or contact number and get some help. Thanks for sharing with us!
Tires drive ok but they are not the greatest. They wear down extremely fast. Most likely why there is no mole warrenty. I have mine for 2 years and 38 891 miles. The belts are showing and ripping causing a bubble in 2 of the tires. I didnt think to look at the tires so soon being the fact that they are 148.00 a piece. Not a cheap costing tire by any means but quality is poor.
Poor traction and noise from these tires were few things we were a little concerned about as well. How was the quality of your ride? Also, if you don’t mind me asking, what vehicle are you using them on?
I have a problem with existing tires. 20,000 miles and tread is already low. No excess usage. Came from factory. Dealership. Are they prorated? Your help please
Hi John,
As far as I know, they are. Check with the dealership and update us on your experience!
I have had mine on now for 61k miles and they are great , rain or otherwise, still have another 10k left of tread left on them but replacing them now, and getting another set, i rotate mine everfy 5k miles so prob helps
