The tyre debate continues

Postby ianoliver57 » Thu Nov 03, 2016 12:16 pm

Morning all. I have a 2012my (registered 12/11) XFS 3ld. It has covered only 18k milage from new. It has 20 inch rims fitted with Dunlop sport maxx tyres. My problem is threefold.
1) they are very noisy on all but the smoothest of surfaces.
2) I suspect I will need to replace them for the MOT in December due to the amount of wear.
3) Braking from 60 - 70 on a damp or wet road feels VERY unsure. Almost like the front end is on ice.
I have had the alignment / traking checked and all is in order. Surely tyres with this milage should be performing better than this and to have so much wear at a very low milage is unacceptable in my view.
The main dealer seems to be favouring Continental rather than Dunlop, but this may simply be due to arranging a better deal for bulk supply.
Any views on what wears well, is quiet and is good in the wet? (I live in Mid Argyll, so frequently have wet roads to contend with!!)

I don't do a big milage, probably about 6k per year.

Regards

Ian.

Ian,

The first question is what tyre pressures are you running at?

The second question is how much tread remains and is the wear even across the tread area?

Toe, camber or caster is important. Caster in particular followed by toe angle has a huge influence on the feeling imparted at the steering wheel. Most garages can check Camber and toe but cannot deal with caster. This can be checked manually with a tape measure and an assistant. Mark a steel tape measure at 114.5" with a piece of tape. Place one end of the tape on the back rim edge of the rear wheel. Run the tape across the axle centres. The 114.5" mark should line up exactly with the rear edge of the front wheel rim. The car will have correct caster if that is the case. If not to that dimension, correction should take place at a specialist garage who have the staff that understand such matters. Correctly set, the car should feel"right" under all conditions.

Tyres do have a habit of going "off" as they wear and age. That is well known. Wet grip can also decrease markedly towards the end of tyre life and noise levels rise dramatically. The effects are amplified with low profile tyres. Low profile tyres do tend to get a bit harsh and squirelly when aged. That happens with most makes.

Continentals are one of my favourite tyres. Dunlop Mxx have also served me well. I like the AvonZZ5 which is a little cheaper than the Mxx. I have a couple new ones on my XJR 4.2 and they perform so much better than the budget tyres that were on the car. I`ve not tried Kumho but BMW fit them as standard and many people have found good results from them.

I`ve never been fond of Pirelli. Grippy when new but skittish and noisy when aged.

I`d suggest premium brands over budget brands every time. Go with a well know name you can trust. There is no definitive answer as to which is best overall. What is good for one owner, may be diabolical for another. Tyre distributors are governed by Law in respect of detailing what a tyre is rated at for ie wet grip, dry grip, noise etc. Price usually dictates most owners choices. Go with a premium brand and you won`t go far wrong. Around £140-£160 per tyre for 20" reinforced, 97Y rated tyres seems to be typical pricing.

New tyres are pure joy as well as being safer and providing a quality driving experience. Ditch any tyre with excessive wear, age other faults and keep a weekly check on tyre pressures. Poor tyre maintenance regimes and incorrect pressures often account for poor handling, disappointment and a few scares.

I expected to replace two tyres per year when I ran a V8 S-type. The chassis is what the XF is based upon and it handles in a similar manner. New tyres annually kept safety up to spec and I always liked the idea of running on tyres that were less than two years. Age can take its toll.

Wow, thanks for that, Mike. Full reply or wot! Re the pressure, they are all at 34psi as specified by Jaguar. They are checked weekly. I am a bit paranoid about soft / incorrect pressures.
Suppose from what you sre saying it could just be the age of the tyres causing the problems. They are the original ones from Dec 2011. Wear is even over all tyres, just thought I should get more than 18k out of a set of tyres.
Like you, not keen on Pirelli. I've always found them ok in the dry, but not in the wet.
I'll try out your measurements but suspect it will be bang on in view of the age, condition and mileage of the car. If not, back to main dealers. It's under warranty till April 2018.

Unless anyone else comes up with a diff view, think I'll try a set of continentals in December.

Thanks for your help.

Regards

Ian.

Hello Folks
Just replaced all my tyres with Avon ZZ5 245/40/19 , I had previously noted on the forum some time past that Mike had mentioned these tyres, previous set were Budget Tyres from China.and the first set were Dunlop.
The first set wore out in 18,000 miles, so the budget set were initially a stop gap. Car has now done 65,000miles and the time came to change tyres. The previous two sets were very noisy compared to the new Avon tyre, they are a revelation, although wearability is still to be proven.
My only problem is with the low profile and no protection for the alloys against kerbing. I seem to have a problem with this ,must be a personal thing. Got to learn to leave kerbs alone.

Interesting to see that your first set of Dunlops wore out at 18k, same as mine. I replaced both my rear at the last MOT due to a split in the inner wall. They were replaced with Continentals, but, since getting them, I have bought a new set of alloys (18 inch) fitted with Yokahama winter tires, so have not yet had a chance to see how the Continentals behave. With the weather we have at present, it may be some time before the winter tires come off!! How do the Avons compare to the price of Continental or Dunlop? I was £420 for 2 Continentals from my main dealer.

If you go to the Black Circles site, this makes a good starting point to review the typical mainstream prices, sizes, specs and costs of tyres.

Once you have selected your preferred brands and costs from BC, you can shop around. In my experience though, BC generally have the best prices going.

The Chinese tyres SAILUN lasted 47,000 and were £64.00p each fitted and balanced. They lasted really well, just down to the depth markers when changed, but were decidedly skittish in the wet and noisy from new. As a result didn't like the car much, preferred my S-Type.
The Avon ZZ5 tyres fitted February 2nd by my local Tyre Dealer in Piddington were £144.00 per tyre fitted and balanced. So pleased with the loss of road roar!! I quite like the car now.

Hi Dave,
Just noticed your location, I'm about a mile from M40 J8a. Perhaps we should meet up and compare notes. You may care to PM me
