would like some tire suggestions just going to keep my stock 17 rims but get a leveling kit what kind of height and width can i run without ripping out the wheel wells

 

Hello and Welcome, If you have an H3 you have either 16" rims or if you have an H3X you have 18" rims.

Leveing kits are a waste of $. Try the Search function above in red.

yea ive looked through several saw alot of height talk but not much mention on the width and they are 16 typo

 

Since you did a search I'd be happy to hep you out;

The 16" HUMMER H3/H3T rims are 7.5" wide. Tallest tire you can put on them without a lift (body or suspension) is a 315/75R16 (35x12.50x16) If you are looking for a wider tire but want to stay with a 33" tire 305/70R16 (33x12.50x16). Hope this helps.

 

In your searches I am sure you have seen that "leveling kits" are a complete waste of $$. Your stock T Bar Keys can give you all the lift you can use.
