Steering geometry with 15 inch wheels

[tforturton]

Once my new wheels arrive, I have to have the new tyres put on, so thought I'd get the geometry checked out at the same time. Looked in the wiki and on the brickyard site and the list of variables seems enormous, but most of it appears to be for vehicles with either 14 or 16 inch wheels. Can anyone tell me what the settings should be for 15 inch? Still haven't decided whether to go for Bfg at 215/75/15 or grabber at 205/75/15, but I guess the settings will be different whichever I choose.
Anyone know of a garage in cardiff area that is used to this sort of thing?

The settings for 14" and 16" are the same, so can't see why they would be different for 15"
It's more to do with centre hub to wheel arch measurement than wheel size

Wheel angles are the same whatever size the wheel is...

Maybe go see Lee at Fred's garage in Llanelli..?

Bit of a stomp, but he'll definitely sort you right.

Sorry Lloyd but tracking for 14" and 16" are indeed different.

just going by what your geometry page says... Just re read it and yes your right, Only read the right hand column (degrees, which are the same) Not the MM in the LH column..

Your vehicle is a 14" so by fitting 15" wheels to it you need to use the 14" settings. The diameter of the wheel will not affect the settings.

16" Syncros are different so use the 14" settings

Probably easiest for whoever is doing it (unless you go to simon) is too put on some 14" wheels so as not to confuse them and let them use the 14" settings then put on your 15"s when your done
