Tyre Sizes

Rough calc.

75% of 265 is 199mm.

70% of 275 is 193mm.

difference in tyre wall height is 6mm, so diameter should be about 12mm larger with the 265/75.

Could you place one next to the other just to check?

Hope this helps.

try this web site it will have the sizes in the tyre calculator ; www1010tires.com. good luck

It would be close to the same height. Just line it up next to one of the other tyres and check the height deferens. Would not recommend running different size/ pattern tyres as it can affect grip, handling also mechanical part’s if big deferens in height.

I would think height wise the tyre would be so close it would not be an issue and only 10mm smaller in width so yes if you MUST use it there should not be a problem.

I would put it on the back not the front.

275 x 70% = 192.5mm x 2 = 385mm div by 25.4 = 15.15" + 16" (wheel) =31.15"

265 x 75% = 198.75mm x 2 = 397.5mm div by 25.4=15.64"+16" (wheel)= 31.64"

So, about 1/2" diameter difference if I've done it right. Near enough to be quite compatible.
