When Tyres Go Bad or Something Else

[Hans Tucker]

Recently, about 15K's ago, I had the tyres on my Honda Accord Euro changed to Pirelli P7's and now during acceleration, from the stop and during the cruise, I get a shudder. I had a wheel alignment done but it is still there and when I enquired with the tyre guys they pointed to a possible bad tyre but could point to which one....really... a bad tyre or something more serious??

Can a bad clutch cause shuddering on acceleration??

Could be uneven wear on the tyres, causing lopping.

I had this same thing with some Chinese made tyres on my Passat. It took about 2000km to bed the blasted things in - HORRENDOUS road noise, squeeling etc. I thought I had bad bearings again.

Worst tyres I ever got though were Continental Conticomfort. Wore out in under 5 months, and I had to have both replaced - on Continental's coin - because BOTH original ones were bad tyres (out of round).

Best I have ever had? Michelin. No doubt about it. I blew a rear tyre recently, and put the spare on. The last of the ORIGINAL Michelin's that the car was sold with from new, 11 years ago. Yes, I am driving on an 11 year old tyre, and it is better than the new junk on there now.

Could be something else, like a broken engine mount. When you pull up suddenly to a full stop, do you notice any abnormal behavior, like the revs dropping excessively low then return to a normal idle?

Best take it to a mechanic Hans,15 k is a years driving for many

worn rack bush , tie rod , theres a few things to rule out and
will only take a mechanic a few minutes to lift your car and have a look.

To check if one of the tyres has gone a little square,run your hand along
the tread on all four and see if you can feel a bulge its hard to see but you should feel it.

I would be suspecting the Constant Velocity joint as well. I recently had the same symptoms on my Subaru and ended up replacing the CVs, all well now.

Matt,

a similar problem to this is quite common on my (and many others') Ford Territory. I'm no expert, but some prowling around the ford forum reveals it can be caused by dodgy sliders on the brake calipers causing the discs to impinge on the rotors, when they should be well clear of them. It can happen on most journeys, but it isn't there all the time.

However, I'm interested to hear your resolution with faulty CV joints. Can I ask what sort of price you might expect to pay to get the CV joints replaced, because the juddering can be very uncomfortable with the Territory.

Any thoughts please?

Cheers matey :)

Just an indication, on my VW Passat (2003), ONE side cost me $275, and that was boots, inners and outers and labour. Took them about 2 hours total.

Cheers Lewis,

That's near enough - thanks for that.

I bought mine reconditioned and fitted them myself, 2hrs + $178 pair for front of Subaru Liberty.

Thanks all but the win goes to those that picked CV Joint Driveshaft. Amazing what difference new Driveshafts make....like new.
