Treadlife with my CSC2s seems premature

[Jase]

Just want some advise on CSC2 tyre wear. I reckon they're decent tyres (noisy though) and I know different vehicles will get different life out of a set of tyres. Just wanted some thoughts on whether my use vs my wear is reasonable, as it has sure surprised me a bit. Perhaps I'm just a bit unlucky?

At the 15K service tyres recorded as front 3mm remaining; rears 5mm remaining. Believe the spec for the CSC2s is full tread 8.7mm & wear indicators at 1.6mm. Got them to do a wheel alignment in addition to the standard rotation (fronts now on back, vice-versa).

Whatever the specs may be, it is very obvious two tyres will need to be replaced before 30K & the other two at around the 30K mark. Wear appears even aside from front & rear differences.

I drive 80% highways, mostly on course chip bituamen & it's driven as a family sedan (no "funny business" & not pushed hard as such).

I guess that given the tyres are wearing evenly, nothing would be wrong with the car would it? That's my real only concern pretty much.

I know VW tested tyres in Iceland on the mkvi to try to improve course chip wear and noise levels. This would make me think the factory fitted ones may be a compomise.
For what its worth I got just over 30k out of the Dunlops on my R32 and I rotate front to rear every 7/10k.

What tyre pressure are you running?

I got just over 35,000 from the front tyres (standard Continentals) on my TDI Jetta. The rears still had more than half their tread. I replaced the front ones (Continentals) and hope to get another 30,000 km plus before I replace all four.

I tend to get reasonable tyre life as I never have the tyres rotated and check the pressure every week - 36 psi.

I have the conti's sport contact2 on my TDi Jetta which has done 22000kms, 85% of it Highway driving and my missus driving it and tread depth left is 6m front and 5m rear. Tyre's where rotated at 15000km and I run 40psi. The car has been flashed for the last 3000km so it has even more toque now and I do like to use it when I drive They are a great handling tyre but the tyre noise and life is not the best. I might try the Sport contact1 next time.

Ive got close to 24,000km on my GT and i reckon the tyres have got 2.5mm left on them all aorundm they were rotated at about 14,000

[Greg Roles]

From new my conti's on the front had worn alarmingly at 12k ( lots of ESP off action ) and I rotated them. They hit illegal at 45k. Your tyres do seem to be wearing quite fast, as I gave mine a pretty hard time till 12k, settled down, left ESP on and still made near 50k.

This pretty much mirrors my experiences with the CCS2 on the GTI. 23,000kms ~50/50 highway/city and ~5mm of tread left. Looks like I'll get 40,000kms+ pretty easily. I tend to go with the traffic flow with the odd squirt.

TDiJetta09 - I've had CCS1s and they are just as noisy as the CCS2s.

What tyre pressure are you running?

Around 38, closer to 40. Keep them up a bit higher than recommended just with most of it "high speed". Which isn't really high speed compared to an autobarn or something.

[Jase]

Thanks for everyones replies. Obviously nothing sinister. Just seems I'm a bit unlucky for whatever reason. Everyone on here is always good for advice or just pitching in with their experience which is awesome.

TDiJetta09 - seems our Jetttas run in a similiar fashion. Your tyres have faired a bit better though. I'm am starting to think about replacement tyres. It's a pain as there's a perfectly good CSC2 spare in the boot but unfortunately the CSC2s are just too noisy. Grip is obviously more important than noise but I'm hoping for more of a compromise in the decibel area.

My CSC2's have lasted 60,000 k's (well three have, one was replaced due to a bulge). Then again, I only have 16's which may be a factor. They def need replacing now. This is going to be expensive (60,000 service incl dsg service and four tyres)

[Dyldo]

this all reads as very strange to me. My CSC's are at 58,000kms now (80% or more highway) with bugger all funny business, stock car essentially, and mine could go another 20,000 kms.
That would mean 75,000 to 80,000 kms out of the set.
I rarely check my tyre pressues too.
Why is my wear appearing to last so much longer?

60,000 is very good. Even though I'm in the polo gti (being a 16"), most of us are also getting between 35,000 and 50,000 out of the CSC2's (driving style would obviously be a significant factor is this mileage). It's just the compound. For highway driving, 38psi is a fair compromise between ride and grip. Much more pressure is likely to make it a little skittish when the roads are wet, thus reducing braking ability. Just stay above the mid 30's (psi).

I've also noticed after an hour of highway driving (cruising at 100km/h), tyre pressure has increased around 4psi on all tyres.

I run them at 42psi. As I don't have sports suspension or anything this still produces a nice ride and even wear.

depending on the profile of the tyre, you'll very likely notice a drop in grip when it's wet - it will make it more progressive when it lets go. That pressure on a low profile is more likely to wear out the centre, unless you corner enthusiastic. I ran 40's on Yoko C-drive in a 50series and it too wore evenly - they also lasted 35,000km and a 10odd track days and some skid pans.

I'll usually run that pressure (42-44psi) for track days, mainly to try protect the tyre sidewalls and also when it slides it's more progressive. Ultimate grip may be less at that pressure, but that's not so relevent to me. Out there for a good time and also have to drive it home.

Best to try a few different pressures for a week each and see what YOU like best. Don't forget to monitor fuel consumption to see how that is affected.

[Jase]

So it seems my tyre life isn't terribly awful, just very low compared to the average life others are getting.

Unlucky it seems with my fairly routine driving

I've been thinking about replacements. I might be hedging my bets towards Michelins or Pirellis as you can still get a good tyre minus some of the noise I've been getting with the CSC2s.
