18" rims and tyres to fit AWD

[vlad]

Hi All,

I am planning to upgrade my rims to 18". Currently running 225/55R17 on 17x7 40+ offset rims. Could people with 18" rims reply with their details to aid me in chosing the right sized tyres and rim offsets. Ta.
Don't know if there are any differences between the J and L/W series so include that info as well.

Car Series:
Rim Brand:
Rim Size:
Rim Offset:
Tyre Brand:
Tyre Size:
Gap between tyre inner shoulder and upper suspension arm of the rear tyres:
Protrusion out of guard:
Car lowered or not:

Here's some examples from AWDs:

Apparently 235 wide is fine on a +35 to +38 offset 18" rim.

I'm currently running 235/40/18 tyres on my 18x8" rims with a +45 offset in the rear, and probably a +31 offset in the front.. the reason why i've got different offsets is because of the Brembo's, and also due to the fact that the tyre place I went to gave me 2 rims with a +45 offset and 2 rims with a +37 offset... go figure! If your car is lowered, you'll get rubbing in the front with an offset as extreme as +31, but the +45 in the rear sit fine (my car is AWD).

So, anything with an offset from +35 to +45 and an 18x8" rim will fit without any issues.

Car Series: KJ AWD
Rim Brand: ROH
Rim Size: 18" x 8"
Rim Offset: +35
Tyre Brand: Kumho KU31
Tyre Size: 235/45/18
Gap between tyre inner shoulder and upper suspension arm of the rear tyres: Enough room, have had 38+ offset wheels with the same tyres - no dramas
Protrusion out of guard: Rear - None, Front - None, but have 1.5 neg camber which may help.
Car lowered or not: King Low SPs.

Car Series: TL VRX AWD
Rim Brand: RJR
Rim Size: 18x8"
Rim Offset: +35
Tyre Brand: Dunlop SP Sport Maxx GT
Tyre Size: 235/40R18
Gap between tyre inner shoulder and upper suspension arm of the rear tyres: Don't know exactly but its clearing safely.
Protrusion out of guard: Front, thanks to the thick sidewall of the tyre about 3mm, the rim itself isn't though. Rear is fine.
Car lowered or not: About 40mm lower than standard.

Lugo, would it be possible for you to take a photo of you front wheels from the top, over the guard to see how much the tyres are protruding. Hopefully mine won't be as bad. I'm going for an RJR 18x8 +35 offset with 225/45R18 tyres which should protrude 5mm less than yours does.

Cheers,
Vlad

Got RJR Blade 18x8 wheels with +35 offset with 225/45R18 Nexen N7000 tyres fitted today at Bob Jane's Gouger St in Adelaide. Interesting that I am able to see a bit (3mm) of the front tyre's sidewall from the top eventhough my tyres are 10mm narrower than Lugo's. I might try a set of 235/45R18 when changing tyres next. I've now got to change 4 x 225/55R18 tyres for the Outlander at $450 each (oem fitted Bridgestone Duellers) or $380 each for Yoko Geolanders.

Sisewall being visible is legal, though. It's the tread that has to be inside the guard.

If you go to a 235/45/18 as your next tyre, you'll have less choice available to you, plus you'll have to remodel the inner guards at the front. Mine scrubbed like hell, even just on half turns.

It's all the tyre that protrudes, the old MA-V1's I used to have didn't protrude at all, the Dunlops on the other hand, well you can see in the photo. Measures about 3mm, sidewall is 5-6mm thicker than the Maxxis that were on these wheels.

Thanks for that guys. Will post a pic tomorrow taken from the top as well for comparison.
