Hello!

I've got a Westfield XTR2 and I would like to fit 13" Radical spec wheels and tyres. But I suppose this is a pretty generic question so any info will be great.

So, if they physically fit on the car and don't foul with anything then good to go?

I guess I'm worried they won't suit the geometry or something, although as you can tell I don't have a clue really.

The radical sizes are front wheel: 7.5" x 13" rear wheel: 10" x 13"

front tyre: 190/535/13 rear tyre: 230/570/13

Not sure if there is a standard size for the westfield, road ones seem to have 15" alloys. have seen pics or more racier stuff but hard to tell what they are running.

Thanks in advance! smile

Dont do what I did, which is buy a set of correct PCD wheels, remember that they need spacers, fit 5mm ones, check that nothing fouled, span the wheels to check they rotated freely, even tightened them up properly.

Completely forgot that with fitting wider wheels and spacers my bolts were too short. Nearside drivers wheel started wobbling uncontrollably after 5 miles as the bolts unwound frown

you need to find out the correct 'offset' this is stamped on the wheel some-where and will be ET followed by a number. The new wheels need to have a number close to or the same as the original. If not the same then a spacer 'may' be required. Co9nsult the manufacturer or supplier for details.

Why not ask the experts - Westfield?

This may be useful for comparing the two different sizes and a nominal hub clearance.

Struggling to find the offset for the radical wheels, and I know the wheels it came on where just random ones to get it rolling. As has been suggested I'll just ring Westfield.

Yeah I guess I'll have to. Whenever I've rung them before they don't seem to want to know. Not rude or anything but just don't seem bothered.
