anyone else noticed MTRs to be bad in wet relative to other muddies?

Hi - Have Goodyear MT/Rs on a constant 4WD Discovery. These are a great tyre and still going strong after 80K k of hard on and offroad driving without a single puncture/problem. However, they've never been particularly grippy on wet bitumen (even relative to BFG Muddies), and this is becoming particularly prominent as they wear down (i.e. the 'lugs' have less flex in them, so the tyre tends to skid more). Perhaps it's the high silicon content which is apparently part of the tyre for improved wear characteristics?

Hi Pathfinder

I have them on my 80 series and one of the reasons I went for the second set was their performance in the wet, I have a set of Pirelli road tyres and hardly ever change them over because I like the MTR's apart from the noise. The only thing is the 80 weighs a lot more than the Discovery and I think that would make a big difference.

Have fun

Craig

Have they grown to be noisy or were they like that from the start. I have heard that regular balancing is necessary to keep them quiet. Mine were very quiet from the start, still quiet 15k later.

Hi, I have found that all big block tyres get noisier as they wear, but I just had my gearbox rebuilt and now everything seems noisy, just shut the windows turn on the AC and up the volume on the radio, great if you are anti-social one like me.

I haven't had to have a tyre rebalanced in years, I have them off regularly and check them for uneven wear and if I don't see any and their is no vibration I can not see the point.

Have fun

Craig

I'd say by 80k the compound would be getting a bit hard and it'd be understandable if they're not flash in the wet. I have a set on my 80 and they're better than the last set of AT's I had in the wet - they were no name AT"s but.

As for the noise - mine were not too bad for a MT but as they wear (approx 20k on them) they're getting noisier and I had them ballanced and rotated every 10k.

The only other thing I can thinkof is that close to 3t of truck with pretty ordinary brakes at the best of times - i drive in a way that tend's not to "test" the brakes to often.

Cheers
Scoey!

I am surprised at your coments. Mine seem fine in the wet. and I thought the high silica was to give them the superier traction on rock not longevity. Most people heap praise on them for there performance NOT longevity. most coments from full size 4wd indicate that around 40k out of a set is about normal.
I have had mine on for a while but I am a bit unusual on this forum I dont really take notice on how many Ks they have done and rarely measure fuel economy or worry about when I bought my batteries

Yeah I'm with you Daveo, mine are getting a little long in the tooth and I have noticed they are not as good in the wet this winter as they have been previously, but personally I foudn their perfomance on wet roads to be amazingly good. I really thought that was one of their strongest points in my mind.

But yeah I've got about 40k on mine and they'd prob have another 10 in them but mine are wearing unevenly because my steering idler is worn. 80k is pretty full on, I wouldn't get close to that out of mine!

from what the missus has been telling me you should have had no worries testing out the wet weather capabilities lately (especially as you are further south now)
absaluuutly perfect weather here in the Pilbarra nights are cool but not cold with clear days in the mid to low 20s

Hehe, yeah I just about needed the snorkel to get out of the driveway the other day! The "puddle" at the end of the drive was creeping closer and closer to the house... It's a bit of a worry when you have non-stop rain, the entire street is underwater and your GPS reads that your house is -1m above sea level!??

The kids can do slippery dips on the back lawn, I don't even have to have a slippery dip! Your feet just sink into the lawn in some kind of black pete type sludge that just looks like lawn.

I have a 93 3-door Disco which is a relatively light large 4WD, so that probably has something to do with it. I'm also running 40psi on bitumen which is probably a bit high for wet bitumen and a light vehicle - although the tyres are wearing nice and evenly which is one of the reasons I'm getting such high kays out of them...

You probably just answered your own question. Running preasures a little high will often improve the wear but normally at the expense of road holding, braking & traction. I would personally rather have those 3 attributes than have tyres that last more than 50K which is about all we are getting out of our MTR's. Even on a heavily loaded Cruiser we would rarely pump them up much over 40psi.
You could possibly do a test letting your's down to 34 & see if there is any improvement in wet road holding although at 80,000KM I would suggest they would be well past their prime.
Both at home & at work all our vehicles shod with MTR's have handled better than other mud patterns in the wet.

I've got to agree with Crackles. I run my MTRs between 34-36psi on road and think they are very good in the wet for an off road type tyre.

ok, you've convinced me. I'll stick with MTRs and just drop pressures during the wet (which isn't too often in Canberra). I'll still run 40psi in the dry as the tyres wear fine (I corner pretty hard so any crown wear is balanced by cornering edge wear!), and I get tyre wear, fuel economy and steering benefits at this pressure...

I have found them to be better than most on wet roads, as majority of A/T's & muddies are absolute crap. I run mine at 34psi, lower than my A/T's, & have no complaints. They are a little noisy, but is to be expected from a reasonably aggressive tyre.

Still amazed at how mileage is No.1 priority for most 4wders. Whilst it is a factor, is not the 'be all end all'. If I get 50k out of mine, I'll be happy. One thing to consider, they are very average in the mud. Work very well on all other terrain, but I would never call them a 'mud tyre'.

Would I buy them again, probably & no doubt if they were my only set of tyres. A pretty good all rounder IMO.

I think mileage is an important factor - given the amount of rubber tied up in a lot of 4WD tyres, it's pretty environmentally unfriendly (not to mention costly) to be throwing them out every 50K kays... Having said that, safety shouldn't be compromised on, and I have probably been running my pressures a bit high for wet conditions...

I've had my MTR's for 2 years and run them at 32 PSI or so everyday of the week. My last set were BFG AT's and they were HORRIBLE compared to the MTR's. The Wrangler is very light, lighter than a disco but i find the MTR's quite good in the wet. I can still flick the rear end out with a blip of the throttle on a wet road but it's much more controllable when doing so ;)

Had mine on for 70K now and will get another 30-40K easy I reckon. Great tyre wet or dry and I recommend them to anyone who will listen to me.
No need for 2 spares anymore and complete peace of mind whenever I go anywhere

I know what you're saying about less need for two spares - I can't believe how much punishment these things take and they don't seem to 'chip' like BFG lugs... I've run them at everything from 10-40psi on all services without a single problem.
