Hmmmmm.
It seems I'm right to be cautious then.

I've called my tyre / MOT place (Jones's in Wordsley)  which I've used for years-since Jack Underwood's closed in Enville Street-you may remember them?

My other local place (QB) doesn't now open on a Monday but I may call them tomorrow.

Thanks Kev,

That's helpful.

My tyres were IIRC fitted to the bike not long after I acquired it.  I think it's got a Mitas or some such on the front and the equivalent of a TT 100 (Dunlop) on the back .I've owned this RS for about 10 years although I've owned others as well over the years.

By any reckoning therefore the tyres are like me and well past their sell by date although I can't detect any cracking and the treads are IMHO well up to the legal limit. The rear though has  always lost pressure when I remember to check it. I suspect and hope though that new rubber will hopefully make the ride less harsh, as along with the snatchy nature of the transmission (inherent in most singles  think) this is one of the minor irritations of the model. Oh talking of which mine has always had a small oil leak from the cam cover head area in a most unHonda manner which I've never been able to cure.

As I said in my reply to Ian I'm very wary of changing the tyres myself . I know of a couple of local workshops who will supply and fit new tyres but I don't think they will offer anything like the choice that Ian's link does. I think I may also need new tubes given the age / difficulty referred to above. 

Like you I only  ride in good (99% dry) weather and am no heavy weight nor do I ride the RS fast or get it cranked over very far these days. I therefore consider as you did that a "performance" tyre will be excessive.

The Kenda seems to fit the bill exactly in terms of price and performance although Ian's link also offer other good priced options.

I'm going to make further enquiries and shall report back when I can.

Thanks to all.

Thanks Ian. That's a really useful link. They seem to have a good range and I'm sure I could find something appropriate. Prices also  seem good.
My problem is it must be nearly 50 years since I last tried fitting a tyre myself and I recall the battle it was. Even in the late 70's there was  a local motor cycle tyre specialist who would do you a deal and fit them.
 The RS250 has DID alloy wheels with very soft rims.
I really need a local ish contact to fit them but if I buy online and not from a local source expect to be stung if not buying from them.
I looked at Wheel House Tyres (Birmingham area) but don't fancy the trip via Spagetti Junction nor could I readily find what I wanted at a reasonable price unlike in your link . I must be getting really old in my outlook!
I don't mind travelling a reasonable distance but the journey has to be pleasant - not stuck in traffic on the M5 / M6 / M42!

Thanks Kev.

What make did you go for? Everything I've seen is coming up rather expensive when you think of the relatively low loads this bike will place on its tyres.

Yes it would be a help to know the size of the front too.

I did look on the website of your local chap earlier today.

Cheers.

Hi Martin. It was all simple in the end as I had the same size rear tyre fitted as was removed. Namely,  110/90/18.
If you wish me to check what my front is size wise, I will have a look tomorrow and report back.
Phil Saunders at Ludlow fitted the tyre for me. He’s a top bloke, old school and trustworthy.
All the best,
Kev
