Unmatched tyres?

[mw3230]

Is it imperative to fit the same brand/model of tyre to the front and rear?

I need a new Roadtec 01 for the rear of my GSA but they seem to be difficult to get at the moment. Can I have a different tyre fitted and still leave the Roadtec on the front

Yes, but no tyre manufacturer will recommend it.

Yep no problem at all, but it is always better to have the same when you can, but if you cannot in this situation, that is fine.

Is that because of safety or profit? Genuine question by the way.

It comes primarily from a safety point of view. The concern is that the manufacturer has no idea of the possible handling/stability issues and prefer to ere on the side of caution.

Technically, if they have been approved for use by the motorcycle manufacturer there "shouldn't" be a problem.

Give you example PR3A was approved fit for Honda ST1100 but shouldn't be fitted to a Trophy 1200, both large heavy routers around similar power etc, but A fit is stronger/heavier tyre which you'd want on a big tourer !

You can get PR4GT but not a PR5 in GT spec, as there is apparently bugger all difference in handling/longevity from 4gt and 5.

If you stick with similar types of tyres, ie road/road etc you'll not have an issue, the worry is someone fitting a supersports back tyre like a Bridgestone S22 and a trail tyre on the front.

Don't forget that you may have to adjust the tyre pressures to optimise handling.

You can't get a PR5 because Michelin like Joan Armatrading dropped the pilot.

I get it, and as someone who has said it is trail5 not of the pilot variety previous, I shall smack myself with a birch stick.

Mea Culpa

You'll die for sure and if you don't your insurance will be invalidated.

The first part might be a bit much but the second part would be very likely especially if you had a big accident

Your insurance will be invalidated. My mate told me; knows stuff when he hears it.

Good discussion and some good advice, thanks all. As it happens when I contacted my local dealer they had one rear Roadtec 01 in stock so I'm having it fitted today. They did confirm that supplies seem to be short however

Out of interest the tyre in question punctured about 2000 miles ago and I plugged it. That and the Puncturesafe seemed to do the trick and several ride outs plus a week enjoying the scenery and roads in Scotland were without incident. Another nail in the tyre yesterday - I decided that another plugging was probably pushing my luck, hence the original query. Still I'm glad to have had the use since the first puncture in what was a fairly recent tyre

I have done a lot of miles with a PR4 on the front and an Anakee 3 on the back...same make.

And, Anakee front and Bridgestone A41 on the back, all without any problem.
