But I understand that using a lower speed rated tyre than that recommended by the vehicle manufacturer would give an insurer sufficient reason to invalidate your policy.
So, a tyre rated at 149mph is not suitable for a thunderbird. I give up.

I don't see why a V rated tyre should be a problem for this bike, either. I've always wondered why the Handbook stipulated only one tyre choice for the bike, rather than a specification, and whether the speed rating was dictated by their choice of tyre rather than the other way round.

There used to be a short list of alternatives on the Triumph website, but I haven't been able to locate it recently and it never appeared to have been updated even when I could find it.

A V rated tire ... put a Tube in it and it is not V rated any longer.

I've never been able to get a good answer to how much the rating should be lowered when you add a tube. Adding a tube makes the tire run hotter, thus lowering the rating. But how much is the question I've never received an answer from any manufacturer about how much.

That said, If you are not trying to travel at 149 MPH, I don't think you need a 149MPH tire. I certainly do like radial motorcycle tires on my bikes.

I have heard that you lower the tire by one rating if you put a tube in it.

Yep, Al.. I've ridden in tropical storms before even, but I have also been to wet and moldy Blighty ;D

Pirelli Dragons are V rated, and somehow Triumph managed to slip those shoes on T-Birds.... but they are radial.

Hi all, also fitting a 110/90 on the front myself...........
Getting harder to find tyres to suit.
Have had the michellin macadam 110/80 & the metzler laser 110/80 previously. Both good, long life.

With outfit/sidecar use, the buggers just wear down the middle.
So I run em totally slick to the canvas to get my dollars worth.

Both front & rear tyres end up square enough for the bike to stand without the stand down, unnattatched from the sidecar.

So I have to be careful when I remove the chair for a solo ride for the first 100kms or so & round off the edges.
Cheers jeff

Tire and oil threads are so fun to read.


I'm no gynecologist, but I'll take a look.
