Will 255/30/20 Tyres Fit Onto The Front Of A Ba Xr6 Sedan?

[LP640]

I've searched and asked around different forums but have had no luck so I thought is try here.

As the title says..

Wheels are 20x8.5 +34 offset. Just wondering if anyone an tell me if they will hit the upper control arm and other inner components?

Also regarding the rears... a 285/25/20 should fit fine on a 20x10 rim +40 offset with guard rolling yes?

Any info would be greatly appreciated!

Thanks!

I beleive the biggest in a 20 is 245/30 that will fit. See here: http://fordforums.com.au/showthread.php?t=25645

Yes and yes +40 is fine for the rear. We have +42. Have had 255 on 8.5 with +36.

Yeah I know of that thread. I tried asking my questions there but no luck.

They're mainly saying a 245/35 wont fit due to the sidewall height which is 85.598mm. However the 255/30 sidewall height is 76.454mm which is only 3mm taller than a 245/30(73.406mm) so that's why I thought it may fit.

Nice! Did you have any issues with the 255s on the front?

What rims did you have and what offset were they?

So the wheels turned up the other day and they sent me +25 offset for the fronts instead of +34

Luckily these should still work with some front guard rolling and running 245/30s whilst still remaining legal for overall track increase. Does anyone have any pictures of BA/BFs with 20x8.5 +25 offset on the fronts?

Also regarding the 20x10 +40 offset rears, I test fitted them and there is maybe 5-6mm clearance on the inner suspension and arm. I was told that since it is so close I wont be able to run a 285/25 Nitto Invo tyre as the sidewalls stick out further than their listed 285mm tread width.. anybody have experience with this?

Thanks in advance!

My BF runs 19" 245x35 front +25mm, 19" 275x30 +40mm rear - no mods. But, there is a way to create control blade arm clearance for rims and tyres:

I've been researching 20" with 285/295 on 20x10" rears for my new FG. The Control Blade arm can be spaced back by 10mm to make clearance for the 285/295 tyres on 10" rims with +38/40mm offset. Use a steel spacing plate on the join in the arm, cut to shape and drill for the 3 holes and replace wtih longer hi-tensile bolts. The yolk in the rubber eye at the front has to be moved over the same distance between the chassis studs - this keeps the arm in the same plane as original geometry. Elongate the innner slot by 10mm, and add a spacer to the outer slot with a large washer so the nut tightens up square on the stud. It would be better to make a steel spacer and tack weld it to the washer so it can't work loose. Or, fit Superpro front control blade bushes and and modify the locating ridges on the yolk bar off-set to suit - avoids elongating the mountibg holes.
