Technically, yes. Provided all I mentioned above are adhered to!

Basically, as long as the tread is within the arch and the tyre is on a rim no wider than the maximum its designed for then no law is being broken.
Mine are 18x9.5 ET38 all round I have to run a 5mm spacer on the front to clear the Brembo calipers which makes the front offset ET33.

I run a 225/40/18 which is a tall tyre to run for this look. Ideally I need a 215/40/18 or a 225/35/18 and a tip is Falken is the easiest rubber to stretch.

215/40ZR18 85W 7.0 - 8.5
225/40ZR 18 7.5 - 9.0 - from tyre makers web-site.


So who's insured now then ?

You can fit 18x10 +38 but it will take a major effort for fitment.

Like this '06 STI Hawk-eye




Note: Suspension just installed this is why the rear tire looks a little to positive.


Daryll had to do major surgery to the rear fenderwells. Cutting, pulling and bonding/gluing the overfenders back on.

You also have to "stack" camber adustment to the rear. This car sits on a set of RCE Tarmac 2(KW V3 hybrids) that have elongated lower camber adjustment holes and a set of camberplates frt/rr. Having the camber adj. on the lower strut clevice allows us to set the clearance between the tire and strutbody. Adding camberplates now gives us more adjustment to fine tune the vehicles camber settings.

The front does not need any fender-rolling but in some cases(JDM Spec C has more caster/longer wheelbase) you cannot run an Anti-Lift kit since this mod will increase wheelbase/caster and you will rub(severe) the front fenderliner.

Specs on this car -3.00 frt/ 2.50 rear camber, this is his track set-up for R-comp tires.
Springrates are 500/400lbs

For example

18x9 +29 offset you will need to do the same mods as above

18x9 +35-only need to do rear fendermodding, no need for camberplates, will need camber adjustment on the strut(camberbolts might need to be added depending on what suspension is being used)

18x9 +45, no issues but not flush looking.


These recommendations are based off of N.American spec cars. Tires widths will need to be considered when attempting to go HELLA FLUSH.

Search is your friend.
I read this a lot but never really hear people say the same when people change the offset of their wheels... So say a 55mm offset alloy with 20mm spacers versus a 35mm offset wheel... any difference in stress?? (assuming same style wheel etc etc.)
