Once you have checked the overall diameter of your oversize tyres, check that they are legal (a potential insurance 'claim' problem)!

In New South Wales: The overall diameter of alternative tyres must be not more than 15mm larger than the largest O.E. size or 15mm smaller than the smallest O.E. size. Minimum speed rating is N (140 kph).

Something you should be aware of.

I run 265/75R16 Cooper ST's on a VZJ95R - it's worth the potential trouble.

Good luck in whatever you do.

Hi. I recently changed from the AT20s over to Cooper LT AT 265/70/17. From my calculations I thought the speedo would be a fair bit out, on a recent trip my GPS consistently showed I was travelling 4kph greater than the speedo. Hence not worth the effort/cost of changing the speedo ... just remember the difference!!

PK,

On my old 95 series the increase in size made the speedo correct but on the 120series the speedo is out by 3-5KPH depending on speed. Just be aware of the speed difference espicially in states where there is little tolerance to speed infractions. Just ask Muddy Doe!
