rotational mass and tire/wheel combo

[HummerB]

i know the 3 came with a warranty on the tires, but i know that i will wear them out way before then. when i replace them i will deff want to upgrade, but how much is too much. i mean the rotational weight difference between a 35 and a stock 32 is noticably i would think. i want to keep the stock rim size but go bigger with the rubber. any sugg?

Heavy subject to get into, so here is a link with some excellent information on larger tires, lifts, etc.

i saw this thread and a lot of it is way out of my expertise, that is if i have any. However, i still want to upgrade tires while degrading performance to the minimum. So, any gurus out there please tell me what the max. tire size i can run without effecting stock performance please post.

Thanks and please excuse my ignorance,

The short of this is that the approximate 3" increase in rolling diameter (32" vs. 35") will kill your acceleration far more than the typical weight difference of a 32" vs. 35" tire.

You will end up with a very slow H3 on the street.
