I know there are hundreds of tyre choice threads. They seem to be about those newfangled radial tyres though. They'll never catch on.

I'm after a set of crossplies or bias belted tyres for my CB250RSA. It feels wrong on radials, and I need to run inner tubes. I like a traditional sort of tyre pattern, particularly as it performs better on rough roads and gravel.

Tyre sizes are 3.00 x 18 and 4.10 x 18, although I can come down to a 4.00 x 18 on the back. In the past I've had Pirelli MT65s, which were awful (and I think radials) and Dunlop K82s, which were great.

Price is the irritating thing. A set of K82s will cost me more than ?90 when they get to my front door (I fit them myself). I can get a set of similar looking no-name tyres for more like ?50. When I last bought crossplies, 6 years ago, there weren't that many no-name manufacturers around. There was Cheng Shin, now Maxxis, and they were pretty crap. Are the assorted budget crossplies as good as K82s now, or do you recommend another tyre altogether that I can get in those sizes?

Oh and a word for the young sportsbike boys who want the newest, stickiest rubber. I could lean my old CB250RS far enough to scrape various metal bits on 5 year old MT65s with the rear worn down to the cords. If you remove weight and power you need a lot less tyre tech to stay on the road.

BT45. Its the only choice. They are the only semi decent crossplies you can get, and they aren't that expensive.

I've got BT45s on the TZR. Can't compare them to other tyres but I've never had any scary moments.

Unless you want to go for the full-on Avon Speedmasters?

I have them on my Enfield and they are oddly grippy. I'm beginning to wonder if I'd just been put off this design by the communist copies of them that my Jawa came with. If you think Cheng Shin were bad, you should try Barum!

I can also vouch for BT45s as being an excellent tyre for middleweight motorcycles.

EDIT: Also consider Avon Roadriders. Pretty sure they are crossply. A replacement for the famous Avon Roadrunners which would have been one of the best tyres you could put on that bike when it was new. Well suited for 70's and 80's Japanese machines

Good sarcasm, but Robby doesn't try to sound awesome on the web, he doesn't try to sound awesome anywhere.

You clearly haven't met him.

You have to know Robby to understand it... he's not doing a usual ped boi thing.

Plus CB250RS pegs are very low. I had a mate who had one and he used to get the pegs down on a regular basis on Cheng Shin tyres.

Possibly pointing out that it's a piece of piss to get everything down on an old CB250RS as many people found out years ago at a PB track day when one pissed on them on every corner. I believe it had a reverse Doohan paint scheme and may well have been at Cadwell. Kickstart probably has the magazine.

I've got Avon road riders fitted on the GS500 at the moment and in all honesty they are surprisingly good, even though the rear is utterly ruined and square enough to look like it's 'fresh' off a sidecar outfit they are still well up for a bit of a hustle on my commute. I could add that they feel a bit vague especially in the rain, but thats likely as much a fault with the bike as it is the tires.

I've got no clue what I'm going to replace them with, I guess Pirelli sport demons or BT45s.

I had an Avon Safety Mileage on the back of my CD250U. Seemed like a good tyre, used to be able to get the pegs down without much hassle. It looked right for that sort of bike, too.

I have, he usually gives the impression of 'trying' quite hard Wink.

As you suggest, you don't need to be going massively fast to get your pegs down. My usual response to people mentioning it is to suggest they adjust their body position and possibly bike setup - it generally hints at there being a problem with one of the two, not amazing riding or tyres etc Smile.

Obviously with a rider on board you won't get this angle of lean, but it feels like it...and thats what matters Smile

If i could find an alternative to the mighty 45's i would...they wear too quick, but offer a real planted feel.

Tonight riding some very sludgy B roads..with a pillion we didn't squirm much. Temp was 2 degrees and the 45s had plenty of flex in them if that makes sense. They didn't feel brittle and skippy like the Avons i've tried.

Avons are good.

BT45s are nice but wear quickly. I find they go very bad very quick towards the end of their wear.

I had a set of cheng shins on a divvy, and they were fine. Not great, but not toilet trip inducing.

As suggested - with the rider on board / going around a corner the suspension will compress, meaning the pegs will touch down even sooner at less of an angle.

I have BT45's on my Varadero, loads of grip wet or dry, they are recommended as the best tyre for my bike. The OE Trailwings have the nick name of death wings as they tend to slip out a lot, the only gripe I have with the 45's is road markings in the wet dont have as much grip but I'm sure I read somewhere that this is true of most bike tyres.

I always found BT45s to have poor grip from cold, which I consider to be very important for a ?daily? tyre, though they seemed ?ok? when warm.
Rather sadly, for many bikes they ARE the best option, but I still wouldn?t consider them a ?good? tyre compared to some more modern designs.

G.

1.) They are the best option as crossplies, and of course no one would consider them a 'good' tyre compared to more modern designs. More modern designs are generally radials though!

2.) Robby isn't going to be wheelying and stoppying a 1000cc sportsbike on these tyres. He's going to be doff doff doffing around London and Kent on a 120kg 250cc single.
