Re: Off Road 18"s

I'm not sure about whether they "scrub", as I'd use that more as a term more relating to suspension geometry. However I'm guessing you're referring to uneven wear on the shoulder of the tyre, and yes, really anything with a very open shoulder is a candidate for this. The larger the shoulder voids the more susceptible the tyre is to uneven wear in this region. Poor alignment is usually the root cause, and suspension geometry can be a contributor too. High camber roads will affect the front left tyre individually.

On a second set of wheels you'll do better with them than as a permanent fitment, as you can rotate the tyres on each use. Appraising the wear and choosing the best location to counter it should see you get the best out of them, however unless you have them refitted to the rim "inside out", the shoulder wear will probably still be an annoyance in time. It'll depend on how many kays you'll be putting on them too.

Based on my personal experience with muds, if I wanted them now I'd buy a desirable tyre and sell them before the wear is noticeable. A badly worn mud is misery!

Cheers,
Steve

Re: Off Road 18"s

I read a lot about people complaining of excessive noise as AT tyres wear. I have little experience in this but I notice that my ATs are very good at picking up and holding stones. I would expect that as the number of stones builds up, so would the noise. I like to pop them out when I can. I can't say for sure this reduced the noise but it can't be good to leave them there.

Thankyou for the insight. By scrub I am refering to the tyre rubbing against the guard or suspension pieces like the strut.
Do you have them on? Any photos of how they fit.

Re: Off Road 18"s

Oh sorry mate... my general comments on this tyre were prefaced with "based on other fitments", meaning other 4WDs I've been exposed to. None of them were JGC.

If you go up in size to a 275 I expect you'll get contact on the rear guard liners, which wears them away almost immediately. I've posted images previously. It's not a huge drama, and there's scope to pin the liners back with a dab of Sikaflex which should help prevent it.

I didn't think anyone had fitted Maxxis Big Horns. Musta missed it!

Cheers,
Steve

Re: Off Road 18"s

Price wise the Maxxis are the same as the BFG AT but I was thinking they would perform better. I probally wont be doing lots of mud work so not sure now which ones to go with.

Re: Off Road 18"s

If you're not driving in mud, don't get muds

- Pros: Mud performance, big horn look, end.

- Cons: Fuel use, noise, wet braking, avoidance handling, usable lifespan, sand performance...

I'm not sure a mud tyre is going to prove much advantage over dirt obstacles when fitted to a Grand, as these things lift a wheel pretty quickly. Tread pattern is irrelevant if it's in the air, only traction control or ELSD is going to help!

Cheers,
Steve

Re: Off Road 18"s

Boxheadmr, you could also look at the ACHILLES DESERT HAWK XMT mud tyre, they also come in a 265/60/18 and they are not that expensive. The tread pattern looks good and the side biters (tread on sidewall) looks serious. I'm looking at these to maybe put on a spare set of rims for 4WDriving (not as a daily driver).

They look good, interested in what prices you have been quoted and what sort of 4wd do you plan on doing.

Re: Off Road 18"s

I've seen them on Ebay for anywhere from $240 - 260
Obviously freight and fitting need to be factored into that.

That's right. In relation to tyres, scrubbing is a testicle term. It refers to the rubbing effect against the road a tyre experiences when veering from a straight line. To a lesser extent toe-in and camber also causes a certain amount of scrubbing but here it's a compromise between tyre wear, performance and suspension sophistication.

Are you scrubbing your testicles on the road?
