Front wheel max cross section width?

[Sullen Merc]

Have a '82 with stock spoked 19" with single disc brake setup and wondering without swapping front ends what the widest tire I can run is?

Any questions or help woould be appreciated! Thanks.

Tire width is dictated by the wheel width and distance between the fork tubes. If you have a stock 1.85-2.15 wheel a 110 cross secton width is maximum.
