tyre choice

i want to try and clear a quick point up about repairs to bike tyres as rob g mentioned it.

1. motorbike tyres that are Z,W and Y rating, by british standards are not to be repaired, PROTYRE (where i work) will no longer repair any tyre that is Z,W or Y rating unless it is a mich, because mich are the only manufacturer that will back us up.

2. tyres that are V rated and below can be repaired no problem.

my personal veiw is that repaired tyres are fine, my rear tyre has been repaired by me and i will run on it at any speed i feel like, i have a great deal of confidence in the repaired tyres. and i even ran my old fireblade at well over twice the speed limit on a repaired tyre.

CBR1000,
Yes it was Protyre that told me of this, which at the time put me off the Avon. Have a word with Neil or Tim to get discounts on tyres for members of this site?

I know them well, little chance I expect

What is the Diablo like in the wet? I dont ride in all weathers if I can help it but you know what its like, if there is a break in the weather...I'm out.

have been caught out in wet once and have to say that the back tyre felt bloody good felt i could still get on the gas quite early

and have found it works well in patchy dry/damp unlike mich(got highsided once when i hit damp patch of a corner

) and have alot more feel all round

I've always suspected it's b*ll*cks spouted by tyre manufacturers and/or fitters to get you to buy more tyres, let's face it, a tyre that has been repaired with a mushroom patch, having had a small hole, is hardly likely to suddenly "blow out", worst case scenario is that the tyre will deflate slowly enough for you to realise there is a problem.

I'm lucky, I have a friendly fitter that will repair any tyre for me, unless of course he suspects the integrity of the carcase to be questionable.

this may not be the best solution for some people but i can supply 2nd hand tyres for most bikes if u are happy to fit them.

for example 180/55/17 Z dunlop 207RR 150 miles off a brand new bike. pun in middle.

things like that almost any make.

you can PM me if u are interested or have a request.

I know this is an old thread but since only joined today it's new to me!!!

This is not bo**ocks spouted by the manufacturers but it is one of those 'grey' area european directives (excitement mounts

)
the reason they are not to be plugged is that performance bike tyres are made with a continuous wound on belt of steel running from one side of the tyre to the other with each strand totally coated in rubber. this avoids heat bulid up between the strands of steel.

When you get a puncture a number of things can happen.

The puncture can damage the rubber insulating the steel strands = heat build up = pop!!!

The puncture repairer (however experienced) first has to make the hole bigger for the plug by drilling. This can damage the rubber/ wound on belt = heat = pop!!

The steel strands could be broken (they are wound tightly together) and this separation affects the handling due to the tyre not doing what it is designed for.

You would never be able to see if any of above had happened.

The other option is that nothing inside gets damaged and the repair is fine = everything Ok.

Bloody expensive hobby this motorbiking lark and dont get me wrong, the temptation to repair an expensive tyre is too great.
Wouldn't do it to your helmet tho' would you!!

Jeeeez....I need to get out more!
