GXlexus470

Can someone please advise if this will fit GX without tire rubbing problems:

Wheel: 20 X 8.5 6X5.5 +18 (size, bolt pattern, Offset)
Tire: 275/45/20 (conservative)
285/50/20 (aggressive?)
295/50/20 (pushing?)
305/50/20 (...?)

I'd like to go 285 or 295 but wasn't too sure. 305 might have problem so might not even go there. 275 is too OEM like... I think? Any suggestion? Thanks.

How about offsets... does too much negative offset messes up suspension or has undesirable outcome? say for the GX: 0 to -18 offset?

I have an 03 GX470 standard (no tmps). Thanks.

285 will look right, also your offset is correct +18, to much negative offset will push the wheel out and with the 285 it will rub.
check out www.sizeitup.com for tire & wheel fitment info, this site has all the info your looking for

bud, do you know if increased or decreased overall wheel diameter ie, using lower profile tires, will damage transmission or other related parts. I know that the odometer will either go faster or slower. www.1010tires.com shows comparison between tires and also suggests not to exceed 3% in overall diameter otherwise you would run into potential braking power loss. That's about what I could research on the net... but damaging trans... that's new. This Discount Tire tech guy is insisting on a 265/50/20 because bigger diameter might damage my trans... I wanted to go at least 275/45/20 or even push it to 285/50/20 on a 20X9 +18mm offset. Any suggestions?
