Second part -- agree entirely, I've never run two sets and have had muds on my daily driver for years with no problems. I'm far too lazy to change wheels every second weekend.Quote:

Modern tyres sure have.
The tyres we are talking about are crappy, over inflated expired hard ones.
Simple really.
I should've added "impractical here, where I live and work".
Two sets of rims/tyres may very well make sense in another situation.
Each to their own.
Andy, Love the suggestion, but I might have to borrow the V8 from your series to do that ;)
I have probably exaggerated how slippery these tyres are... Just that when they were new they stuck like glue - even in the wet - and were better than any HTs or ATs I have tried. They are still safer than any 7.50 cross plys I have tried (original fitment). And safer than most 235s I have run.
I just measured them - minimum tread depth is 8-9 mm. Tread wear is even - which means they aren't overinflated - despite insinuations to the contrary.
I have found ths same as Rick - higher pressures helps traction in the wet.
The IIA is a mainly an offroad toy, so sees very little road/highway use (except when it is called in to cart firewood)...
My other "car" has (new) Maxxis Bighorns ;). They don't grip quite as well as the MTRs did when new, but still better than most tyres.
Mike - if you look closely it should say that is the max pressure to use when seating the beads. Not the max pressure in use. [EDIT - just checked and MTRs do state a max pressure = 50psi]. When new, I tried pressures in the 30's. The supple sidewalls of the MTRs flexed too much. When I pumped them up higher the on-road handling improved significantly. The same goes for the bighorns on the 110.Quote:

As you say, this the roads have been very greasy of late - due to the first decent rains in about 6 months. So maybe the tyres are not to blame... I will try them again after the next lot of rain.
ditto. I've had to run significantly higher pressures on road with the Big Horns than I ever did with BFG MT's, the case is much more supple.Quote:

The last three sets of MT's have been comparable in grip on road to the BFG AT's on the Patrol, and don't chip as badly either.
I know the frustration. When I bought my Lotus the car had NEW tyres on it. Unfortunately they were 10+ years old. I was driving down a hill near me at about 30k in the wet one day and tried to stop. Not a chance. I eventually managed to pull it up but I nearly jumped out I was going so slowly.
I just bought some new ones. Due to the tiny size of them (by todays standards) it was only like $400 including tubes. It doesn't make sense to have old tyres on a sports car.
Also, tyres are legally supposed to be used within 5 years of manufacture I believe. Someone may be able to confirm this? The manufacture date is stamped on them. I was told this is because the rubber cracks which can allow water in and rust the steel belting leading to failure.
I drove home with a friend in our MINI's one night in the pouring rain. He had cut race slicks on (just enough groves to be able to drive on the road). I thought he was going to go off but he had heaps of grip - more than me on full road tyres.. It shows that compound is very important in the wet.
To be honest, I have never heard of this tyre "use by" date before... In fact I know an old German mechanic who stores new tyres in the shed for 2 or 3 years before using them - so they would "last longer"
I doubt very much that it is a legal/rwc requirement. As I have put several vehicles through RWCs over the years with no issues. I am some of these vehicles would have had tyres over 5 years old. Even in Germany, which is one of the strictest places in the world when it comes to RWCs, I got a golf roadworthied with VERY old tyres, and it passed (though with a comment on the form that the tyres were old). I replaced them shortly after. NB - I always carefully check all my tyres for defects, etc...
I found this thread...
Expiry Date on Tyres @ ExplorOz

Any evidence of this???Quote:

This is not an Australian article, therefore a bit irrelivant to our rules and conditions.Quote:
