Car tyre question

buzzing147

Strange question this maybe, but I got 2 new tyres yesterday, same make as tyres on rear of car, I was looking at the pattern and noticed after I drove and parked again, one of the tyres actually must of moved on rim?? Because the brand names on both tyres were level before I left! ie looking at the 2 tyres they were in line in terms of pattern. But when I returned, the brand name on front tyre is now opposite the rear tyre. Does that make sense?

Er, Are you serious? thats what happens when you drive any car.

So u mean the tyres actually move on the rim? Comparing the pattern of 2 tyres on both sides of car cause same brand, and they keep changing after driving! I thought tyres stay intact with rim

When you drive, and turn a corner, one wheel has further to travel than another. Thats what caused it.
its normal.

This happens even when both wheels are on the same side.

For others, Its a easy mistake if you dont stop and think about it

The tyres remain on the same place on the rim, but when you drive then the wheels on right might spin more (for example when you go around the corner the wheel on the outside moves faster).

This should explain it better https://www.youtube.com/watch?v=XABkgTWacPo

The whole wheel is what rotates at a different speed, its why cars need differentials! If you turn right the the wheels on the left side of the car have to travel further than the ones on the right

God I'm silly! Good job I posted it here before going into tyre centre and getting them to match tyre pattern again front and back!

They would have sent you out for a left handed screw driver, a bubble for the spirit level and a glass hammer to fix it.

Cheers mate but it was a serious question lol

Got the 2 new tyres for front and put 2 slightly older front ones to rear

Then looked at car and said to myself, why on Earth didn't they match the tyre writing on both tyres!! Was about to go back in and request a match up, but luckily I posted thread here first!!

Always put new tyres on the rear....

This is true by the way.

Only if you believe it. I don't believe it and always put new tyres on the front of FWD cars.

Depends on the car. If it doesn't have any electronic safety features I place new on rear and if it has I don't mind so much.

I get the logic alright, that in an FWD drive car, losing the rear is far more problematic than losing the front. On the other hand though, the vast majority of accelerating, braking(weight shift) and cornering forces go through the front wheels - so I'd put new tyres there.

OP, while it might seem very obvious now, there's no such thing as a stupid question and you're always right to ask if unsure.

I always put new tyres on front, back ones were down to thread passed NCT with advisory 8 months ago but kept them on, no bother with them, 2 ones on front are only 5 months old so changed them to back, and set new ones to front. I think car would look strange with 2 new tyres on rear and 2 older ones front.

New tyres on rear.
I understand people think new tyres should be on front for better grip, but its actually better to have better grip on rear tyres than fronts.
There are many reason, you can google them all, but the main one is to decrease the risk of skidding in wet curve.

Esel

Most or all major tyre manufacturers recommend putting the tyres with most tread on the rear. There are a few exceptions.

In this case the "old" tyres are on the back are only 5 months old so I don't see any advantage putting the new tyres on the front, but normally I'd put the new ones on the rear.
