hey guys,

I'm just looking for a subtle staggered set-up with 18's on a 1.5'' drop that doesn't need any fender modifications (I can roll my fenders if I really have to, but I'm just too lazy right now :P).

I was thinking maybe 245/265 40 series at the most?

It's worth it to roll at least the rears... then run 245/40-18 front on a 8 or 8.5" front wheel, then 275/35-18 on a 9.5" rear wheel, +30 to +35 all around

I see I think I'll probably go with that then...

btw a quick question on speedo accuracy...

If let's say, your front wheels' size gives you -1% error and your rear wheels
give you a +1% error; will they compensate each other and cancel the errors?

Or is the speedo just based on the rotation of the drive wheels?

yes. 1% speedo error is very insignificant.

I have 18x10 +24 in the front with 235/35/18. It rubs.
You'll have to roll/shave your fender.

275's up front with a +25 offset will fly with Vertex fenders. A rolled stock fender would probably clear a 235/245. That is about it.

alright cool, thats what I was thinking, in my previous post i said the +25 origin fenders, unless i can find the vertex...

what about in the rear, same thing 18x10 +18offset, how much would i have to go through to get the 275 to fit? or should i get the +38? would be odd to have that setup for front and rear, no? I will camber, but it IS a DD.

+18 is going to struggle to clear a 275. You may get a narrow 265, but you are probably going to need a 255 to get it to fit. +38 is pretty conservative. If you could split the difference, that would be perfect.

if you are looking at work wheels, I believe that they will make just about any wheel in a custom offset.
