the q is getting ready to get some new tires this month,up to now I have been using Michelin pilot xgt v4 in 225-60-15 size,generally getting about 30000 miles per set,big question,what are the tradeoffs of going with 235-60-15 xgt in an h rated tire other than max. speed rating,which would you choose and why?by the way,I have never had to flip the directional tires,they all have worn evenly.

If you can live with the wet weather characteristics (I certainly can't!) of the Pilot XGT V and XGT H, then the 235-60/15 H will be a slight step up, I would think! They will certainly fit fine on the stock rim.

On the other hand, you may want to try the Firestone Firehawk SZ50EP at 225-60/15. They are slightly cheaper than the Michelin's at TireRack and you may be amazingly blown away (as I was) by the overall performance - both dry and wet. Superior to the Michelin's, IMHO. My current set of SZ50EP lasted about 20k miles or so.

Keep in mind that the speed rating has very little to do with how fast you intend to drive... It's a measure of the strength of internal construction, and an H-rated tire isn't gonna withstand the severe abuse a Q hands out.

I would think the load rating would be more indicative of the (95 or higher) tire's strength. Probably more important than the letter (at least between V or H).

True.

Per Dennis, they go hand-in-hand.

Have used 235/60/15 H4 for the last 4 years as do all T3 mobiles [4 in all all Q]...........we get 30,000 miles to the bars........I rarely hit 130 mph [23 seconds of acceleration from 60 mph] but I have tried them for a minute or so.....before recommending them to members.

Current have the last 2 AVS I on the front and H4 on the rear [10,000 miles on each].

The Question is are Michelin H rated tires stronger than other H rated tires = YES and are Michelin 98 load rated tires stronger than every one else's 98 = YES and are Michelin 98 stronger than 95V rated unless subjected to the heat generation of over 130 mph = YES.

Now wet braking is another factor which Michelin has always chosen to trade off for other factors. Will a 300 treadwear in the same brand stop quicker in wet than a 400 = YES, will a V rated 300 stop shorter in wet than a 400 H rated = YES
