Offset

[healy]

Just bought some 35s maxxis bighorns I'm running a 15x8" -22 offset if I get the same style rims will it be ok

[nissannewby]

Should do but it is gonna rub simply because they are a larger diameter tyre.

[healy]

Yeah I expect the rub but I was thinking more offset would it be better?

[MudRunnerTD]

I would not go any wider than a neg 22 mate. You start to put a fair bit of pressure on your CVs and drive train with a bigger offset

[nissannewby]

That and if you go a bigger offset you can then have dramas with the tyre touching the outside edge of the guard before it touches the chassis in the rear.

I've mentioned it a few times on here about something called the Ackerman Angle of the tyre/rim (google it). The larger the offset, the more we screw with this angle and it creates wheel wobble (not good for more reasons than just being a pain at the steering wheel) which people try to get balanced out, change bushes, etc, etc only to find the wobble is still there.

It's not overly common and seems to be vehicle specific (a mate has a patrol similar setup to mine, but has -30 or something and he gets the wobbles bad through 80k's to 100k's whereas I have -22 and don't; others have bigger offsets than that even and don't get wobbles, so not sure how it affects some and not others, but it does and should be at least considered when upgrading).

I have a neg 44 offset on a 10 inch rim and I get the wobbles at about 60km

I think we need a new member "wobbles" as we already have a "clunk"

[healy]

so there 35x12.5 r15 stay with the 15x8"??

[nissannewby]

Yeah bud stay with the 15x8" they will work a treat.
