I have to replace a single rear Tyre due to a slow puncture - do I need to have the same brand / speed rating tyre?

If I don't will there be performance issues?
 
Are the other tyres worn at all? Ideally you would change two at a time but if the other, opposite tyre is fairly new still then you can get away with just one. If that is the case then get one as close as possible to the other tyre. Keeps the reactions of the car safer.

If the other tyre is worn then definitely change two as otherwise it could be a bit iffy. Going into a wet winter you don't want to mess with your tyres.
 
Certainly the 'best' way to go!

Otherwise there are possible imbalances/differing reactions being introduced.

It's ok to have different styles/brands on front from rear though.

And if it's solely for driving in London, it won't matter a jot!! :rolleyes:
 
punctures can be fixed ,at a very cheap cost compared to a new tyre.
take it in and see what the experts say ,shouldnt take them more than five minutes to see where the puncture is ,and if it is in an area that can be mended.if its coming from the beading they should be able to clean the rim and replace your old tyre .
how do i know ,i worked in a garage that fitted tyres.
as for same make and speed rating ,no ,need for same make ,but you will need the speed rating to coincide with the cars spec.
 
First thanks for quick responses - quicker than when I post my golf related drivel....

Anyway all tyres are in decent shape, I was just worried about putting a different brand (Avon) with the remaining 3 Bridgestones

I have to drive up north on Friday so couldnonly arrange an Avon at such short notice

ive taken it in and it can't be repaired - is it an issue having one tyre with a higher speed rating i.e. W instead of V
 
Have you got a full size spare? If so, how would matching the new tyre to the existing spare and putting those two across the same axle and demoting the part worn to the spare? I wouldn't put a brand new tyre on individually, I'd always put a pair across one axle.

How do you drive? If you are in London, abiding by the limits then it will probably make no difference at all. If you are taking it elsewhere and pushing it a bit, you might notice the difference.

I can't see anything in the Construction and Use that would prevent the mixing of speed ratings or manufacturers provided all the sizes are the same and the speed ratings are at least the minimum recommended. I personally wouldn't do it (old habits die hard), but that's just me. My only other thought would be were you to be involved in a serious incident (God forbid), would it afford your insurance company some "wiggle room"………...

Thanks for the detailed response! I'm in SW London but do head up and down the A3 and around the M25 a fair bit (as you know lots of nice courses off the A3). But I tend to stick to 70mph!

I don't have a spare - full size or emergency tyre, just a can of tyre repair fluid!

Sounds like it's not a good idea to get a single tyre of a different brand....
 
Sorry been watching this thread with interest to see the general opinion.
Firstly if there is a large difference in age buy 2 and put them across the axle.
mixed brands front to rear and vice versa is okay.
Across the axle - no. Tyre suppliers have different philosophies, weights will be different and a tyre is rotational mass making it a greater issue. Patterns are different grip level, turn in response can all differ. Not all tyres marked the same behave the same.
Difference in speed rating, well that's the speed the tyre can cope at it's load rating for a period of time. Usually there is a mass difference between tyres with different speed ratings - check the load rating! You may have to run at different pressures - may cause balance issues at all driving speeds.
Bottom line buy 2 tyres that are the same and put them on the same axle.
Depending on your brand of car, it may be more affected overall. Tell us what it is and model year ( colour isn't important).
I have worked in tyres for nearly 20 years, from top end motorsport to prestige car manufacturers. The effort that goes in to getting the right tyres and the factors the tyre is used to tune would amaze you.

Thanks for this answer - I just have a standard Nissan Juke...

So are you saying I should have two tyres of the same speed rating across each axel? Or try to make sure that all tyres are the same speed rating?

thanks again to everyone

I know this one wasn't aimed at me, but having read harpo_72's reply about the construction and the potential weight, grip & other differences, the more it convinces me to stick with exactly the same specification of tyre on each corner.
 
it depends and how much tread you have on the opposing tyre and if the two opposing tyres have directional tread.
directional tread usually looks like diagonal lines going into the centre of the tyre

ask the tyre centre.
 
I will chuck a spanner in the works.

What if you have a modern car with all the whistles and bells? Some have sensors that now detect wheel speed/rotation and can independently apply the brakes at different pressures on each corner of the car depending on grip etc. Surely this would mean that you could have any make of tyres on the car as long as the speed rating is correct.

A bit lateral, but didn't Formula 1 teams used to use different compounds/grip of tyre in some races depending on which track they were at?
 
As mine is a company car I have less choice in the matter so if a tyre needs replacing it is just that one they do. I have had mixes of brands but they have been of comparable spec and speed rating and no real problems. Mind you, most of my mileage is spent ploughing up and down motorways.
 
You may want to check the small print in your insurance policy. Mixing different spec tyres may invalidate your insurance, certainly different speed ratings may be questioned as you are not sticking to the car's original specifications.

I work for an insurance company.
