235/85R16 Tyres

[Monaro Pete]

Has anyone ran this size? I see the rolling circumference will bring the speedo in line to the correct speed.
Was the clearance ok & did you have to remove anything like mud flaps?

Mine are 245/75/16 which equates to 30 and a half inches, I have no probs with them. I think Rick runs 32s or just under on his truck, I'm not sure but I've never heard him say he's had problems with 'em.

235/85 are popular with green ovals, work out at 31.7"

useful as all height, same width, so keep existing 16" rims.

those that use them usually remove flaps, might need to flatten seam in arch
and 2" body lift useful.

On the tire says they are 31, but on measuring them they are less, as per what barbeast said even so they hit front and rear of front wings on occasions, Rick
