New Wheel And Tyre Setup Help!

[Benny Beard]

Hi guys getting new rims this week for my 07 IS250 RWD the specs will be 19/8.5F and 19/9.5R.

What would be the perfect offset to get and what spec tyres? I have no idea of the offset I should get but I was thinking for tyres I should go 245/35/19R REAR and 245/40/19R FRONTS what do you guys/gals think? Any help would be great. TIA

hi mate if you want run flush with 19/8.5F and 19/9.5R go +20 but if you want be safe then go +25 - 30
with tyre sizes you can go 245/35/19 rear and go 255/40/19 rear, rears usually bigger size for more traction

Standard 19" wheel sizes would be 225/35/19 and 255/35/19. They're what I had on my 19" f sport wheels. You can go for 235/35/19 fronts and 265/35/19 rears with no problems though the fronts MAY scrub on full wheels lock but otherwise bumps and normal driving won't matter.

I run 19 x 9.5 at +22 which sits slightly stanced at the front.

I'll see if I can find a pic for you.

Fronts only are 9.5 +22. Rears are 19x11 +25
