Jon what are Trac edge tyres and what have you found are good
sideways tyres. I think I will now have to invest in a set of MTs, but now
what ones are good at preventing sideways motion while giving good forward
grip, ah the choices.
SNIP
JB they are the type of tyre (although its a name given by one
manufacturer) that has thick blocks around the edge of the tread that
are 90 degrees to the carcass, think of tractor tyres but blocks just
round the edge. There are usually two continuous ribs running round
the centre that take the greater part of the wear when running on the
road. So when it comes to keeping straight instead of slipping
sideways you just have the narrow central ribs to do that and the
blocks to do the work pushing forward, the tyre slips sideways cos of
the gaps between the blocks around the outside edge with little
back-up from the two narrow ribs in the centre. When on the road the
central ribs take all the wear, so correct pressures are vital.
As for the right tyre to get over that problem, then I will defer to
others who have greater experience than me. (I see Julian has got
big knobbly Goodyear MT's that he likes - yes Julian? And he does a
lot of mud wallowing in the shooting season). I like the Pirelli
Scorpion range, and would fit them if I could afford it. Otherwise I
seem to get into a lot of dodgy places - and out again - using Cooper
AT's and my old Dunlop Grand Treks. The Turkish Lassa AT that I had
to fit in an emergency the other week looks like it will do the
business, but I will have to wait and see. (They are a company owned
by BF Goodrich and fitted OEM on the Turkish made Land Rovers). In
our work we always use a good AT tyre that handles heavy mountain
downpours well when driving the sometimes two hours out to the field
on tarmac, and we rely on good staff training to get where we want
to when off road, not big knobbly tyres that would not be the safest
for the majority of road travel.
Again, I think we all advised you to get a set of cheap knobbly
remoulds to put on your spare set of rims, to be used just for your
playdays, with your regular AT's for everyday driving. I think that
the money you save over the cost of expensive knobbly ones is better
spent in you getting more experience by going to the play area every
Saturday. Spend money on gaining experience not some rubber with a
fashionable name. With that use, you will never wear the knobbly ones
out and eventually be king of your local bog's mudpit !
As for Salisbury, see my reply to Gareth last week.

Hey Jon
Thanks again for that info about the tyres. When I read and reread what you
have said it makes sense. Most of the MTs are made that way with the rims of
tread onthe inside and the lugs on the outside. I was looking at the General
MTs which are a good price and seem fairly chunky but not sure now if the
tread pattern is correct to prevent side ways slipping. I have thought about
the retreads for the off roading but have read they are very hard to
balance.
Also from what I can gather from the previous dicussion about this it seemed
to be the opinion that rubber tyres deteriorate with time and exposure to
light. So if the retreads have old side walls then they will not last too
long being that they seen there use by date anyway.
Is this not correct.
Also if the lugs set at 90 degree angles on the outer rim of the tyres push
you forward what would prevent slidways slip, lugs pointing in
the( ) direction.
I agree about the training, he is running a full days training sometime soon
for 100 euro. So I will think about it. But it is amazing what you are
forced to learn when out on your own.
I found out later that this was his first open day to the public so it was
as is for the purpose of training and may need some adjusting to cater for
the public. Because as has been said the cruiser does have the power but I
can only imagine some poor sucker in his Rav4 or similar doing the course. I
also found out one of my lockers is not working , just kept flashing at me,
dirty thing.

Hi Jon and John,
Yes I have Goodyear Wrangler MTs and personally wouldn't have them
again as a day to day tyre. I find them too slippery in the wet on
tarmac, very noisey and not much use on slippery mud and grass.
Having said that there are few tyres at standard tyre pressures that
are much good on slippery mud and grass. I guess I would have better
luck if I dropped the tyre pressures, but the opportunity to lower and
raise them isn't always there.
Next time around I'm going to go back to BFG ATs which perform
perfectly adequately on the slippy stuff and a good on the road and
then if I get around to getting another set of rims with splash out on
some Extreme Trekker style tyres for if I want to do some serious mud
playing, which is very rare.
One of the key things with the BFG ATs is the tyre pressures. Many
people seem to run them at very high pressures around the 40-45psi
mark, I think for economy or something (not really looked that deeply
at is but a quick search of the 80 list archives on Birfield.com will
bring up some reasoning), but at that pressure I found they preformance
on slippy mud, slippery roads was diminished.
If, however you run them at the recommended pressures for the car (off
the top of my head around 30-32psi) they perform a lot better.
Actually in hindsight I think part of the logic of running higher
pressures, particulary if you have oversized tyres, is that you get
greater rigidity and a more positive suspension/steering response, but
personally I'm not that fussed.

I run 33 BFG AT's as my daily tyre and I run them at 25 psi.
A teeny bit wallowy but the grip is superb, especially in the wet and no
sign of uneven wear.
