Well you never said "anyone in QLD....."

This is a rubbish photo (and not mine), but it was taken in pouring rain, from where the car slid back to after failing the climb. Scary.



We didn't have anything with properly narrow tyres on this trip, but this is the stuff where too much ground pressure is barely enough. Slick clay, no ruts, and 75 metre stretches between drains.

It's all about RPM, wheelspeed and being able to steer under power.

I have just bought 30's and they are on 15 x 7 rims.

Yet to put them on Jimny though.

Ive just picked up set of these up in 235/75 15.. Main reason been price, and the fact there a skinny tire compared to other 235/75 15..... I wanted a 29inch tyre, at 7.5 inch wide, but could only get Simex or Swamper in that size. The couragia I hope is going tobe thin enough i can keep wheel speed up, been under geared. They measure in at 28.6".

I run FC's 235/75/15's and couldn't be happier with them. They seem to grip quite well in dirt and aren't too bad on dry bitumen, but they are SHIT in the wet. I have lost control a couple of times on a wet road when I wasn't expecting it. Ended up pointing in a direction I wasn't aiming for. So BE careful!

I guess this would go for any larger chunky tyre but just my experience.

Once I get gearing sorted, I'd like to go 31's, and i would consider FC's again.

EDIT: I probably will need to invest in a big break kit to.

when you blokes are talking about ground pressure, what are you referring to?

If tyre touches the ground over a larger area, for the same weight,
ground pressure is lower.
Probably good thing when you don't want to sink, like in sand,
and a bad thing if you want tyres to bite into the ground, eg in greasy clay..

no worries, thanks for the explanation

Had a set on a patrol I sold, didnt like them, rubber id on the hard side so wet rock pull you up pretty quick but they werent to loud on the road and didnt wear quick. But I think you need a heavy car to make them work well
