I was looking for some tyres for different cars. There are measurements like 20x10 I can see but how do I know they will fit on the wheels because there is a size missing for the dimension of the ridge in the middle of the wheel. I have many spare tyres but see the inner wall ridge size are different widths and do not interchange. There need another size to be given on a spec doesn't it? Maybe like 20x10 plus x8 (as width of ridge)? So I can not find any tyres to buy even on the well known slot site for all the sizes have only two meansurements. There is Paul Gage tyres also except no choice for Scalextric and some other cars I have measured with caliper.

Welcome to the ongoing nightmare of tyre sizes! These threads may be of some help or they may confuse you even more!

The wasp list is useful, thank you. I don't know if I will buy some for £6 each tyre! £24 per car! No! Excuse me while I buy lottery ticket.

Same information is in the other threads, but repeating here for convenience
MOST wheel makers have a 1.1mm drop to the shoulders, and that is what the major slot car tyre makers use as a base for their tyres.
Most 10mm wide tyres are for nominal 8mm wide wheels - and have a centre width of 5.5mm, and 10mm wide wheels may have a centre width of 5.5mm and up.
Urethanes such as Paul Gage can be made in smaller numbers, which allows them to fit tyres for more odd ball wheels
If you put the car brand and model and the dimensions you wish to fit into your post, it would help people provide you with answers.
And copying my content from another thread.
Some tyre makers and resellers also put the O.D. of the tyre when fitted to the range of rim diameters, just to make life and re-checking even easier.
eg
Slot.it
DWG 1171 mould size
Approximate diameter on hubs prior to trueing
15.8mm hubs 19.7mm
16.5mm hubs 20.3mm
16.9mm hubs 20.6mm
17.3mm hubs 21.0mm
Of course, gluing and truing will alter this a little.
