What's the biggest tire that can fit on stock rim?

[VX KAT]

I need to put new tires on my '01 Ironman and I was told the largest tire size I could go w. my stock rim is 245-60-R18's. I've been reviewing them online, but they don't look like anything too fancy, not to mention they're expen$ive.

Anyone know how big I can actually go with out rubbing my wheel wells?

Thanks!!

This is probably among the most asked question on here.

Your RIMS are 18" x 7", your OEM TIRES are 245/60/18.

Use the SEARCH FUNCTION and you'll find a ton of info, what works, what doesn't, issues, etc...

As Tom said, the trimming required for 285/60-18 is SUPER EASY and you can do it in 5 minutes with a dremel.
This is it, a tiny triangle shape piece.
I did NOT have to make any change to springs or turn the TBs.

I've studied this exact question for years and here's the definitive answer(s) using the 2000/2001 OEM 18x7 rim:

VX at 100% OEM Stock Height (non-lifted) = 275/65R18 (32" O.D.)
Some minor interior-side cladding trim will be required as VX-KAT has illustrated. An All-Terrain tire or Street version tire with smooth rounded shoulders will have less interference than a muscular square shouldered Mud-Terrain tire, so take that into consideration.

VX "Lifted" = 285/75R18 (35" O.D.)
Important Note: The 285 series width is the absolute widest tire that can still be "squeezed" onto the OEM 7" width wheel.




If you absolutely don't want to cut/trim your cladding; but are after a wider/meaner stance, then consider the tire size of 285/55R18.

Thanks for all the helpfu tips and the link. I haven't mastered the search function yet. When I tried it it kept sending me to VX's for sale and spare parts.

Anyway, if I trim the cladding and put the larger tire how much larger am I getting with the new size? It is just an inch or so? I'd hate to cut up my stock VX for .5-1" if thats the case.

I'm looking in to the following tires thafit stock:

Goodyear Assurance TripleTred All Season Tire - 205/65R15 94H VSB

Falken ZIEX ZE-912 TIRE 245/60R18 105H BW

Cooper WEATHERMASTER WSC 245/60R18

Nitto - NT850 Plus CUV

Firestone - Destination ST


Let me know what you think or if you have any suggestions.

THANKS!!

I'm running the Firestone Destination AT. It's a very good tire from my experience so far. You can't use mine as a guide though because mine are 33x12.50R15 with an abundance of offset.

I just wanted to let you know that basically it's a good tire ... but I've heard good things about the other tires as well.

BTW, to fit the 33x12.50s requires a 3 inch lift & some trimming as well.
