Do you want taller gearing or just more tyre on the road?
If more tyre on the road then go for a 100/90 tyre as the rolling circumference is more or less the same as a 3.50.

yes they will still fit on 10" rims ...thats what they are made to do...
there are now many makes available of 4.00x 10 tyres with far better profiles /tread pattens etc than were available back in the old days..

Use Avantone's gear calculator it's brilliant. It's on here somewhere.
