    Default WK grand, max tyre size for spare?

    What is the max tyre size you can fit under a WK Grand in the stock location? Looking at a 32.1" (255-70-18") set of tyres but want to use the stock spare mounting location. Searching is giving mixed views.
    Cheers

    I had 255/60R18 (30") and it just barely fit under there. If you stow your spare in semi-deflated state........ maayyyyybe it would fit, but I doubt it. I had a rear spare carrier made with my bumper before increasing tyre size, so there's no point testing now, the original tow hitch is gone.

    I have a 245/75/17 in there no issues. But it is deflated. So I keep the compressor in the vehicle.

    Thats the tyre size i am running now and I can easily get my fingers all the way around it now (Maxxis AT). May have a look in my lockup, I think I have a couple of 31" tyres in there on none WK rims, will see what fits.

    I take it it won't fit inflated then? What is the tyre model?

    Do you have the standard tow hitch installed? I'm thinking back now and I think that was where it was a little tight for me, so perhaps without one it will fit nicely.

    It the Jeep is the 2007 year then the 18" should fit as it lifts up under the Jeep?
