new tyres

[VivP]

i recently replaced the rear tires of my 5er but now the car feels very loose around corners.:smashScreen::smashScreen:

i had Michelin PSS and replaced it with Toyo proxes and feel that the car just don't handle right.
do the new tires still need to wear in ??

please help

Hi Shailesh,

I will try answer you question as simply as possible.
Firstly, I am assuming you replaced your tyres with the same size and profile, and also assume you replaced because the Michelin's were worn out. That said ...

If your Michelins were worn, the tread blocks are virtually non-existent. A new tyre will have a much thicker (comparatively) tread block, and this does tend to move about. This is normal, and compared to a worn tyre, you would have no movement in the tread structure.

One might think "but they were always that way", but believe me when I say a driver gets accustomed to the progressive change in feel that he does not notice it. Any person who has fitted new tyres for the old, will always notice a very big difference in the "feel" of the car. The tread blocks "walk" across the road, giving rise to a feel of looseness.

The other point to consider is that because the Toyo is a so-called "budget" brand, the cost savings are achieved in the manufacture. You more high-end makes will use either a 2-ply or "fold-over" construction, whereas the less expensive brands could utilise a single-ply construction. Also, the material used varies from brand to brand, with the high-end brands using Kevlar, as opposed to Nylon, Rayon or Polyester. Kevlar is very stiff, and with this and the construction, increases the "stiffness" of the sidewall of the tyre. This affects road holding, lane-change stability, as well as comfort.

Should you have the same tyre size as the Michelins, as in width, rim and profile, then I would suggest that you INCREASE your tyre pressure slightly to compensate. A higher internal pressure will increase the stiffness of the sidewall. Just don't over-do it, but do a trial an error, and don't over-exceed the maximum tyre pressure specification. As the tread blocks wear down after a few months, you can then systematically reduce your pressure until you achieve your desired level.

All the above is mentioned quite apart from any alignment or suspension structural damage that you might have, so have that checked first.

Hope this helps,
Cheers !!

To add some advice here: put your new tyres on the front wheels (if they are not staggered) as my experience is that when i put new tyres on the back the car feels loose. When the new tyres are on the front the problem is usually solved. I am talking about my experience. Try it, see if the car's handling isn't back to normal with the new tyres on the front.

thanks guys for all the reply's.

will start with the pressure check and from there
