The perils of old tyres

It's not illegal here to have old tyres, but I agree they can be very dangerous.  They might look ok, but they won't grip because the compound's gone hard.

I've got old tyres on one of my cars and they looked fine.  But when one of them deflated, a whole lot of deep stress cracks opened up that you couldn't see before.  Quite horrifying and very nasty.  I certainly wouldn't want to be on them around a tight high speed bend; and they'd be like ice skating in the wet!

What is currently driving me nuts is the fact tyre manufacturers aren't making tyres in the sizes we need.  Unless you have 18-20" wheels they're an endangered species....


Having a great run with Kenda tyres in 14 inch Mark and my Mondeo runs Kenda 235 45/17's on the rear which have really made a difference in Handling too, Pirelli's on the front that are a few months old and seem ok but the rear Pirelli's were only half worn and a bit twitchy in the wet so the Kenda's were a nice surprise.

I also have them on the Volvo's but a 205, 65/15 inch and they are doing far better than I expected there so worth a look.

Silica compound tyres are now pretty much the norm too and chatting to a bloke in the car club who works with tyres was an education, He says that he is seeing 1st generation Hankook Silica tyres now nearing 11 years old and the casings are as good as new showing no signs of perishing although for safety sake they only resell them as trailer tyres but stacked next to Non Silica compound tyres he says its chalk and cheese.

Back when I had those old tires, I couldn't figure out why my steering wheel was shaking back and forth. I took in my vehicle to a shop that does nothing but alignments to get a 4-wheel-alignment and find the cause of the steering shake. The shop told me that I needed a new steering box. So, I bought a rebuilt C&M unit and installed it. Same problem.

Then I took the vehicle in to the Mercedes dealership to have the steering wheel aligned so it would be centered with the wheels pointing straight ahead (I brought the centering pin for them to use in the steering box). The dealership pointed out that the tires were out of round, and that was the cause of the vibration. I wonder why the alignment shop couldn't figure out that one. I was also upset that that set of five used tires that I just paid nearly $300 to have installed after labor and tax were no good.

I drove the car on those tires for about another week before I noticed one of the tires had a bubble coming up out of the tread, so I had to install my spare. Then the car started shaking and hopping badly, so I installed two super old bald tires and steel wheels because it's all I had and I couldn't afford to buy tires again. I was finally able to save up for the five new whitewall tires I currently have on my car. Even though they are budget tires, they ride better than any tire I have experienced on my cars, but then again, I've been used to using almost nothing but tires at least ten years old.

Once these tires are worn out, I want to save up for a set of real, high-end wide whitewalls.

A good shop should have looked at the tires first.  Another tire-related issue is a pull to right or left.  Interestingly, the tire carcass can be misshapen enough to cause a pull to one side either coasting or even sometimes only under braking.  That means a good shop will also rotate the tires first before checking other items for a pull.  Its hard to find somebody competent these days so if you find a good shop that knows this stuff, stick with them.

I thought the tread on those Dean Alpha tires looked familiar, so I checked into them  Seems to be made by Cooper.  The last shop I worked at sold what looked to be the same tire under the name "PR 812".  Since they were cheap, I ended up with a few sets.  They did not fare well in the Georgia heat and I had more than one that had belt separation issues.  I had one of the cars parked for a few months on a concrete driveway and had one tire where the tread completely delaminated from the carcass.  It just peeled off sitting there.  That set was less than three years old.  Then again, my cost as only about $30 each back then so...

Driving around on bald tyres?  You guys are mad!   ??? :o  BTW it's rare that a FEA issue will cause tyre shake, shimmy or vibration.  Wheel balance is where I'd look FIRST

  Was running old Michelins myself till recently. way, way way past their use by date.

1st week of May I got off my rear end and found the answer I was looking for.

couldn't afford the same brand so settled for these Hankook, (made Korea) and what a difference. Got the right size for my rims too.  (Thanks Carl)
Best part was the manufacture date..........4612...........cant get any "fresher' than that!

Better to be running a lesser brand in great condition than persisting with unsafe older tyres........whatever brand they are

My 450SE still has the Michelin XDX it left Sindelfingen with in week 41 of 1979, as spare.
I dread the day I'll have to use it, even though it looks reasonably well. New tyres are coming soon though :)

I have Hankooks, too; 185/70R14s with the side of the tire ground off to show the whitewall underneath. These should work until I can afford real wide whites.

Are the tyres designed for that?  Here it's not legal to modify your tyres.   ???

MrK can you get 215s or 225s in those tyres?

It doesn't affect the tire at all to shave off the 1/16" of black rubber on the sidewall. All the strength is in the white rubber and casing. No laws against it here, and hotrodders have been doing it for decades. Still, I'd prefer to have the real thing.

I'm also liking the narrow 185 tires. I guess my car is prone to more body roll or whatnot, but it makes steering effortless at low speeds, and it does improve fuel economy quite a bit.

Regarding tyres, I would simply not drive a car with old or bald tyres other than perhaps directly to a tyre shop.

It's absolutely not worth the stress, or the risk.

My mother has eight year old Pirellis on her A-class that are in dire need of replacement. Tread is delaminating, and I have expressed my immediate concern.

Squiggle I'd want something in writing from the tyre company to say its ok to cut into a tyre like that, before I'd do it and have the confidence that they're safe.  Here it not only leaves you open to fines and Defect Notices, but it can also affect your insurance

Mark, not sure on the larger sized Hankooks. (215...225 etc)
I got mine from JaxQuikFit tyres in Moorabbin.
They're Aust. wide so give em a call if you're interested in finding out.

Well I've bitten the bullet and went 4x professionally refurbished 15" Bundts and will put 4x Dunlop Sport BluResponse 205/65 R15 94V on them, as soon as the lot arrives from Germany. It wasn't cheap short-term (actually, on par with buying 5x R14 Vredestein Sprints), but will pay off long-term. I'll report back on the tyres as soon as I drive them a few miles.

Those are my new rims :D

No luck with Hankook.  Sounds like Maxxis make a 215/70R14 (MA1) but they're only rated 96S (180kmh).  Should be enough unless you head to the salt flats!  Quoted $179ea x4 fitted.  Apparently they're also a whitewall on one side!   :D
