On this site there are two bt45's that would fit my bike and one's cheaper than the other, but does anyone know what difference the 'B' in there makes?

[Guest]

Its the speed rating. Not sure which is which but one will be made for faster speeds than the other.

[Decor58]

I thought that at first but B isn't a speed rating

could also relate to older compound tyre

For the sake of saving £4 which would you get then?

[eastanglianbiker]

if you are going in to buy the tyre have a look at them both and on the sidewalls there is a date code all tyres have this in which case go for the latest date code In the example above:

DOT U2LL LMLR 5107

DOT U2LL LMLR 5107 Manufactured during the 51st week of the year

DOT U2LL LMLR 5107 Manufactured during 2007

Idealy you want tyres with last 2 numbers being 09 or 10

I am gonna hazard a guess that it is a BMW oe tyre. Hence the K1100LT after it.

Same applies to tyres for Jags and Porsche

The B version has a reinforced sidewall and is BMW OE. You don't need it unless you have a particularly lard assed bike

Sounds like what Dan has said then!

Like it

[Decor58]

The BMW version is cheaper then?? lol

If that's the only difference I'll go with that one

[eastanglianbiker]

is the bmw tyre not squarer at the edge of tread like the harley and goldwing tyre?

[Guest]

I'd go with the normal one Rob, not the beemer one. Might find its a bit hard as well as possibly squarer like Steve suggests.

[Decor58]

In that case it's the normal one!

Thanks for the info guys
