Re: Top Speed?
BTW- You may want to look at the rating of top speed on your tires. I'm not sure if they are speed rated over 90mph? CAn someone verify this?

Looks like they are "Q" rated:

"Q" speed rating denotes 99 mph as the maximum sustained speed.

Re: Top Speed?
I believe, and the chart at Bridgestone verifies this, the 285 tires do not have a speed rating. Speed ratings symbols are not required on light truck tires. Therefore, they probably fall under the R rating which is 206 mph (used for HD truck tires). This would seem logical, since GM caps the top end of all their vehicles about five miles under the tire rating (unless you have a ZO6  )
H rated tires are usually capped at around 125.
In addition a tire is good shape will not blow up if pushed past the speed rating, and a tire that is not in good shape (especially under-inflated) may blow lower than the speed rating.

Re: Top Speed?
I did a little over 90 mph about a month ago in Md. I too wonder what was the top speed on the Hummer H3. Drove pretty good too at 90 mph.

I think you did a typo on the R speed rating...shouldn't it be 106? |
