    If you were only going one size wider maybe but if you are putting on extra wide tyres the rim will be smaller as the tyre will be higher. eg. changing from 13 36's to 18 30's

    What size tyre do you have?, you could go with something like a 70 profile tyre, that will give you a wider tyre on the same rim but keep the same diameter/rolling circumference

    e.g. 16.9 R38 is the same tyre as 420/85 R38, but you can also put a 480/70 R38 on the same rim, it has the same diameter/height but is 6 cm (over 2 inches) wider.

    Sorry for hijacking tread.
    I have 18.4 r34 tyres they are in bad shape. Can I put 16.9 r34 on? A mate has 2 decent ones that I can have.

    If it's a 2wd tractor, no problem. If it's a 4wd, not unless you change the front tyres as well. The 18.4 has a larger rolling circumference than the 16.9. It will affect the 4wd cause the ratios will be different.

    Thanks
    I kinda thought that would be the case. I might just keep a look out for a second hand 18.4. Even one would do cos one of them is badly split

    The ones on the front are in good shape 40-50%
    If I was to find front ones what size would I need?

    Bumping an old thread here but can anyone tell me if its possible to go with a wider tire. Currently the fronts are 13.6 R28. Can I go to 14.9 R28 without the need of changing the rim??
