Tire size ?

[Mike Curtis]

What is the meaning of the numbers on the tires for example 100/90. By all that I read my 850 uses a 100/90-19 front but PO has put on a 110/90-19.
What difference will this make?
Thanks

100/90-19

100 = width of the tire in MM

90 = Height of the sidewall of the tire, expressed as a percentage of the width ( 90% of 100= height)

19 - Rim size in inches

So, your 110/90-19 is a little less than 1/2 inch wider than the original, and slightly taller (very slight). It could be slightly slower handling, but if it is not rubbing then it should be fine.

The 110/90-19 that you have on the front is OK.

When you replace the rear tire don't go with an oversized tire. Look at the clearance that you have on the left side of the swing arm and you'll see what I mean.

Like Jay said, you can use the 110/90
Just be careful as to how large you go in the rear.
If it uses a 130 rear, stay within that range.

You don't want the Cheng Shin tire? Or want to go back to a 100/90?

No I have a IRC Durotour RS310 130/90-16 on the rear & I want to match tread patterns and manufacturers.
