Certainly do - I'll be swapping back to them after I've finished with the 235s for my big lap

Hi guys, I'm currently looking at replacing the tyres on my Puma and am looking at the 255/85s. How do these fit without any lift etc, do they rub anywhere? Also does anyone have any opinions on the KM2s??

Thanks Ant

Ant,

KM2's are beyond doubt the quietest and hardest wearing mud tyre on the market. They handle road and gravel like AT’s and mud and rock is sorted with ease.

This is an often discussed topic and there are many, many threads that will get linked during the discussion!

Bottom line is that the 255/85/16 is a great tyre for looks, handling and extra diff clearance. My first choice if my car was out of warranty.

Which brings me to the problem with them; LRA will not honour warranty on the drive line if you have them fitted. If your Puma is in warranty the 265/75/16 or 235/85/16 would be a much better option as they are both (the only) LRA approved sizes.

I have the 265/75/16's fitted and you can see my Stornoway Grey 90 on the "Show us you Deefers" section to see what they look like.

The fitting of these tyres now has my speedo matching the GPS for vehicle speed which was previously 10km/h difference at 100km/h.[/QUOTE]

So it is always showing( 10kph ) faster on the dial than reality. It is not allowed to show slower.

So the GPS says 90-95kph and the dial is saying EG: 100-105kph.

Correct?

Pretty much it for a Defender from a 200Tdi on when going from 7.50/16's or 235/85's to 255/85's.

285/75/16 have a 32.8" Diameter which is only an inch higher over standard but slightly wider at 11.2 (not sure if that fits on the standard rim).
Either way something to think about.

Yep, but with the extra width they may rub, depending on the wheel offset and you need an 8" rim (legally, although I know of a few people that have squeezed them onto 7" rims)

255/85 is slightly taller than a 285/75 (most around 33.3"/new) and can legally be mounted on a 6.5" rim, so LR HD (Wolf) rims can be used.
