Hi,
Has anyone out there successfully fitted a set of 31" tyres to a Holden Frontera? (Factory are 30".)
If so, did you have to change the wheels? And if you did, what brand etc. did you get?
Factory rims are only 6.5" and I figure it'd be best to go to at least a 7" width rim.
My preference is steel wheels, but I can't seem to find any suitable ones on-line.
Thanks in advance for any help.
Cheers,
Benn

From memory the Isuzu MU came stock with 31's so you should be fine. Not much of a jump from 30 to 31 inches though, is it really worth it?

Hi Gary,

You're right about not much gain ... maybe half an inch in ground clearance.

Main reason for the switch is cosmetic.

I just completed a 3" suspension lift and the 30" x 9.5" tyres look small under the car.

I'm not in any hurry - still plenty of tread left - but I'd like to go up to 31x10.5 when the Coopers need replacing.

Cheers,

Benn

Which Frontera?

I have 31s on my 1997 Rodeo on 15x7 ROH Track 2 rims.

Hi,

I've got a Frontera S, 5-door - built in 2000 - with a 3" lift.

I'm guessing the ROH wheels are alloys?

I haven't yet found steel wheels with enough off-set to fit. (Factory is 24mm +ve I believe.)

Anyways ... thanks for the suggestion. I'll check them out.

Cheers,

Benn

Your 2000 Frontera will be different to my Rodeo I imagine. However the ROH Track 2 rims are steel. They are the rims everyone seems to refer to as Sunraysias. Don't know the offset measurement but they are refered to as a Navara offset.

Remember that the offset you will require will change with any change in rim width.

If you want to go to 10.5's, a 7" rim is an absolute minimum. Some tyre fitters may not fit tyres to rims if it falls outside the manufacturers guidelines, and if you are buying Coopers, kiss you warranty goodbye.

Hi Guys,

Thanks "Utemad" re: the info on the Rodeo ROH rims. Haven't had a chance to check them out yet, but will do.

And Gary, re: rim width ... I've checked a few websites on tyre specs and you're right about 7" being the minimum. (I can't really justify new alloy rims - which is why I'm looking for steel ... and they're less prone to fatal damage.)

I'll give some thought to the off-set requirement - hadn't considered that. The main issue is clearance between the tyre and the wheel arch body work on full lock (not against the chassis/suspension components).

Basically, the bigger the track width, the bigger the problem.

Again, thanks for the input.

Cheers,

Benn
