Yeah. I actually found a set with a 29.5mm....I think we need like a 34mm or something close so less than half a cm isn't going to make a big visual difference lol

I don't think half a mm is going to make much of a difference though.

Nah, it's +29.5. I did see a member running 275s on a cobra wheel that looked fine. Didn't really stick out or anything.

what do you mean? if your flush now and you add almost a whole inch going out it should stick out by almost a whole inch. right?

How did the member with cobra wheels run 275s without it sticking out? Maybe your backspacing is way different or something.

34mm minus 24mm is 10mm, which is just over 3/8". It would look fine in the rear, but 3/8" more out in the front may look funny...
34mm minus 29.5mm is 4.5mm, which is just under 3/16" - not noticeable to the average joe...

You should be fine with the 18x9 and 29.5mm offset. Should look perfect.

yeah, thats what i said... the OP said 29.5mm offset, plus the wheel is 9" vs my 8", so the extra 10mm offset, plus the .5" of extra width (the other .5" is sticking out the inside) is .89" total sticking out vs my wheels...

didn't the person with the 275's have a GP? maybe they have wider fenders... plus the offset is what confuses me... mine is 40 on an 8" wheel... i think if i used a 255 tire, they would stick out considering my 235's r flush... i wish i had a wheel with around a 45-48 offset... every wheel i've seen is 38-40 with an 8" width... anyway... back to the original subject...

i think on a gxp its a whole different thing. the spacing on the gxp wheel has to be different and its an 8in wheel not a nine inch plus the fender has to have more room. just speculation on my part. i really wouldnt **** with 30 or lower unless they were free, but good luck i expect pics regardless.

GXP front fenders are "wider" than non GXP Grand Prix fenders. Now whether that relates to a "wider" fender versus a Monte Carlo or not is purely speculative.

You'd either need official measurements or straight up test fitting (trial and error).
