Tyre Sizes - Rough Guide Thread

215/75/15 with a 2" lift should be no problem. Have you got front mud flaps?

Yes I do have mudflaps. After posting yesterday I realised the garage had inflated the tyres to 30psi so I deflated them to 23psi and went over some big speed bumps and they didn't scrub, so I'm not sure if that has fixed it?

I run mine at 20psi front and rear. 15psi doing proper offroad. Remember the larger the tyre, less pressure required.

Ah I did not know that! Thank you.

Hi Everyone,
I'm the owner of a 2017 Jimny, all stock, trying to get good mods for it!

About tyres, I saw a lot of people putting 215/75/15 and I always wonder about performance.
I agree most of Mud tyres are on this size and the extra clearance will be an advantage but how about off road usage?

I take for granted on road the car will be slower, just for the extra weight and size but I'm interested about sluggishness, slowness during offroad.
Is 215 good for that or although extra clearance, everything else will be worse? climb slopes? will be the 4W-L too long?

thanks in advance!

215 isnt that much bigger. Its a common choice because of tyre availability at a decent price and choice. The gearing isnt greatly affected. 235 can be run (i know of one lad who does and he manages ok off tarmac, but it is slow on the road).

Mine had 215 BFGs on when i bought it, so i dont have any real comparison to the standard size, but this link should give you some idea what the change will be:
