What size?!
Hi all,
I’m currently running a set of all terrain koala 4x4 tyres on 16inch rims, but they look too small and are affecting the speedo, they’re currently 235 70 r16, on a defender 90 1990. What size should I have to fit my speedo and what size would people recommend using for the best mileage handling etc.

The size you need is either 235/85 or, possibly, 7.50 x 16 if you're using standard steel wheels.

If you're using standard LR alloys then 265/75 is also a common size.

I think the difference in mileage between the sizes would be marginal, at best. Tread pattern is likely to make more of an impact but even that won't be huge. Darren

I have a 1990 200tdi with the lt77 gear box if that helps?

Looking to get alloys instead of steels so I guess it’ll be 265/75 then

265.75R16 or 235.85R16 for alloys on your tdi would work well. both near as the same OD, one set just 30mm wider. Cheers
