There are also wider rear intended tyres available from Proline Rob... called 2.0's so these can be included in confusion along with the new SC10B type narrow fronts
It shouldn't matter, but as is written it can be read that you should have same tyres (pattern? compound?) all round, or same wheel size all round or the tyres have to be same sized all round (kourse kings are slightly wider than schueys so couldn't be used as front/rear combo)
It's easier to say any commercially available width wheel, 2.2 outer bead, 3.0 inner bead and any commercially available tyres/inserts... sticking wide tyres on narrow wheels is pointless and the narrow tyres available are radials or dirt tyres which will have no major advantage over existing tyres.
I've got nowhere to mount a rear wing cos of my 'minimal' cut outs!
