i've got a question for you guys........

I am buying some boyd coddington smoothie 2 wheels (17X8F and 17X10R). What tire size should i get for the fronts (or do you think i should run 17X10 up front too?) And, what size Nitto DR's will fit best on the back??

thanks

I'm running the Boyd Timeless 5's, and I have the 17x8's up front with a 245/45/17" Nitto. IMO, it looks GREAT. On the back I'm running 17x9.5's with 275/40/17" Nitto DR's. You could go with a 285 if you wanted as well, but a 275 would still look good.

When deviating from the stock tire setup you should consider the changes/differences in tire height. Here's a formula that I use to calculate tire height:

(tread width x aspect ratio) divide by 25 to convert from cm to inches for the sidewall dimension, x 2 + rim diameter = tire height.

Example: 245 x.45 = 110.25, 110.25/25 = 4.41, 4.41 x2 = 8.82, 8.82 + 17 = 25.82" tire height.

the height of a 275/40-17 tire would be: 25.8", making the 245/45-17 and the 275/40-17 a near perfect match.

As I understand it, if you have too great of a difference in front/rear tire height, ABS problems can crop up.

I run AFS Polished ZR1's 17x9.5 in the front 17x11 in the back. Tires are 275 Nitto 555's in the front and 315 555R's (DR) in the back.

Absolutely an AWESOME street combo! No problems!

thanks for the info guys. I sent an e-mail to th wheel mnufacturer abou offset, and this is what they sent me....

The Smoothie 2 comes in 17x8 with 4" to 6.25" backspace and 17x10 4" to
8.25" backspace.

What do you guys suggest for back spacing? How about if i ran a 315 DR out back (how would tat look on 10 inch wheel?)?? Would i want a different backspace than if i ran 275's on the back?

I just dont want the tires to stick out past the fender. just a hair inside them woul be perfect.

Thanks
