Guys,

Just realized I have the older style (non-radial) tires on the TY175. Can I put a standard 4 x 18" IRC radial on that bike?(yes, I know I will need a tube). Almost looks like the it won't clear the swing arm.

Thanks in advance.

Unless your TY175 has a seriously bent swingarm or an offset rear wheel, yes a modern 4.00 x 18 competition radial rear tyre will clear the swingarm.

Make sure you get the tube type IRC tyre - they make both tube type and tubeless type rears.

You were correct, tires went on with no issue.

Question: Are the wheels/hubs the same on the 175 and 250? They sure looked like they are identical.

Thanks for the comments.

Hubs and spokes are the same for all TY175s and TY250 twinshocks.

Two different front backing plate types (one with brake wear inspection hole). Two different front brake arms (one steel, one aluminium) and same for rear brake arms.

Rims are a different kettle of fish.

There are at least two types of TY175 front rim and at least three types of front TY250 rim. Rear rim range similar. Some TY250 rear rims are the same as TY175 rear rims. All have 21"front and 18"rear. The choice of rims by Yamaha reflected in some cases the rim type being used on their MX and Enduro bikes being produced concurrently, and in other cases the rim type was chosen to meet road registration design rules in some countries.
