Hi All
Is it ok, to have a higher speed rating on one tyre, than it is on the other if on the same axel?
I’m after a new front tyre for the nearside front, as about a month ago I also had replaced my offside (drivers side is this correct?) as I had a puncture.
However I can only seem to get a replacement tyre, which is a higher speed rating.
The one I’m replacing is
BRIDGESTONE Turanza ER30 93H
The one I can get either as a only choice or cheaper!(?)
BRIDGESTONE Turanza ER30 93 V (IIRC)
So my question is, as it’s a higher speed rating but the same manufacture and model of tyre does it matter if its higher than the tyre at the other side?
And
When I went to a online check out for the tyre I was never asked if its for the offside on nearside, does this not matter also?
Many Thanks

As long as you adhere to the max speed rating on the LESSER tyre, you'll be OK.

Tyres can have inner and outer tread patterns but not left and right sided.
|
YES.
You will find it came with H rated and the tyre manufacture will make a huge batch of V rated for a higher spec car so yes you can mix but not if the other way round if it came with V as standard no H can go on if the speed of the car is over 130mph.
|

....but to be sure, you need to check the car manufacturer's recommendation as to speed rating. If they specify H, then V is fine as this exceeds the specification. If the manufacturer specifies V, then you already have a problem as you have incorrectly fitted the H-rated which is lower than the manufacturer has recommended, and in this case you should really replace both.

They can also have a specified direction of rotation. Unless you have a tyre with both, which probably doesn't exist for normal applications, no problem with that either.

If a tyre has an inner and outerside then it HAS a specified rotation.
|
|
No it doesn't. It can go on the other side and then it will rotate the other way.
|
Thanks Guys – The manufacture tyres came with H Rating as standard which is anything up to 130mph as far as I’m aware so if I cant get the H rating one then I can buy the higher speed rating with confidence
And I certainly wont be going higher than 130 mph

If the manufacturer specifies a minimum of H rated tyres, then fitting a V rated tyre to one corner is fine. As mentioned above, it's over and above the minimum specification for the car.
If you had fitted a lower speed rated tyre than the manufacturer recommends then this might have some implications should the car be inspected by the police following a serious collision.
Oh, and yes, offside is the same as driver's side. Nearside and offside refer to the sides of the car near the kerb, and not near the kerb, respectively. Hence they are the other way around on LHD cars :)

You're welcome RV.
I get part-worns on the Escort, rarely the same make and usually a mixture of directional and non-directional. Unless you're going to swap wheels from one side of the car to the other it makes no difference as the fitter will put the tyre on the wheel the right way around for the side it's going on.
Be thankful you don't drive a Lamborghini: With wider tyres at the back than the front, and left- and right-handed tyres to boot, each corner has a different tyre requirement. Which is why they carry a can of gunk and not four spare wheels :)

......and a thick wodge of cash for new tyres!

Even if you had a spacesaver spare, there's nowhere in a Lamborghini to put the punctured tyre.
It might fit on the front passenger seat, provided you were driving alone.

Actually.....
AFAIK the British are the only people to use the terms nearside/offside, and anyway, the term would differ depending which side of the road is driven on, Thus on a LHD in the UK the RH side (passenger side) is still going to be offside......

Tyres are either rotational, asymetrical or symetrical. Rotational tyres must only rotate in one direction so once fitted to a wheel can only be fitted to one side of the car. I they need to be fitted to the other side of the car then they need to be refitted to the wheel. Asymetric tyres have an inner and outer and therefore once fitted to the wheel can be fitted to either side of the car. Symetrical tyres can be fitted any which way on the wheel and accordingly any side of the car.

I remeber when I was 17 (and stupid) and all i would request was to "throw a couple of 14" (IIRC) Remoulds on" for my Mk1 Astra from my Local indie - and that car would get thrashed about.
How things change - now im choosing the correct sizes, profiles model of tyre, im now introduced to speed ratings and I try to drive properly all the time and will only stick with the correct and good quality tyres for my car - saftey comes out tops, not stupidity.
