Yes, generally speaking, H-rated tires tend to be a better quality than T-rated tires, for example stiffer sidewalls. I don't plan to be driving 125mph too often. But, I do a lot of sustained long distance driving in 90F degree weather. In the past, I have been happy with Yohohama Avid H4, BFG Comp/TA HR, and General XP2000 HR in a 70-series tire. Alas, all of these companies no longer make an H-rated tire in P185/70R14. My research shows that... Sumitomo HTR200 is classified as High-Performance, not High-Performance & All-Season like most other H-rated tires. Firestone Affinity LH30 is classified as All-Season, not High-Performance & All-Season like most other H-rated tires. Alas, even the new highly acclaimed T-rated Performance & All-Season Yokohama TRZ is not available in P185/70R14.
