Sumitomo HTR Z III
Follow-Up Review: 12,500 miles on tires
Following up with my review after nearly one year! <br><br>I am definitely impressed with these Sumitomo tires! The tread is holding up..and after 1 year they have lost only about 10-15% of their dry/wet traction. These tires have done a fine job protecting my 20 inch wheels. NJ has some of the most vicious potholes and the rims were only subject to slight bending thats barely noticeable when compared to the previous Michelins. Yes folks, unfortunately I was surprised by some of NJ's hidden potholes lol. Recently, despite the minimal damage I decided to have the front wheels replaced (in order to have a back up set) and I commend Sumitomo for protecting my first set. Rear wheels thankfully were subject to zero damage. I highly recommend this tire due to cost, performance, reliability and wet traction. <br><br>While I rarely ever do burn outs (yet another reason why they are treading so well)...I did finally get a chance to test the tire in the M5's P500S mode (against several 'rivals' namely the Nissan GTR, EVO X and Porsche Panamera Turbo) and they performed wonderfully! Wet traction is definitely an improvement over my Michelin Run Flats, the Michelins would have lost over 25% of their traction in comparison, at least on the M5. Conering was an improvement, but not enough to get away from the Porsche on inner ring cornering. :) <br><br>Nevertheless, these Sumitomo tires are very strong and this has to be my first year ever not getting any nails, slow leaks nor punctures in my tires (knock on wood)! Thank you Sumitomo! Will buy again within 6-12 months!
Initial Review: 200 miles on tires
Very comfortable tire so far. I have driven with the M5 in normal mode setting and the tires have been phenomenal (haven't tested them in P500 mode). So far I have driven through dry and extremely wet conditions and this tire performs even better in the rain. They appear to outperform the 19 inch Z rated Michelin Pilot Sport A/S tires I originally had in both comfort and durability, and the Sumitomos have a smaller sidewall.
Unfortunately, I haven't done enough driving to review the tread wear yet but I will update this review as time passes, I can attest that noise is low, traction is very good and the sidewall does a great job of protecting the new 20 inch deep dish Dynamic Performance rims I installed with these tires. Overall, I am very satisfied and would buy these tires again, in fact I'm thinking of buying one spare for the front and one spare for the back (staggered).
