I just purchased ASA JH3 rims and Dunlop M3 tires. My front tires are 225/50/R17 98H and the rear are 225/55/R17 97H. What does the 98H and 97H (heavy load) indicate and are they normal for the G35 coupe with Brembos. Do they have any impact on driving, safety, etc?

Anybody have any experience with this total package?

Thanks
