Been helping my neighbor Jamie find? a new set of tyres for his 75 Norton. Major porblems!

Original came with Dunlop K81 4.10 X 19.

1st Pass - Bought a set of Phoenix tires thru Coker that were supposed to be the correct size. They were actually 1.5 inches lower than stock. The ad never made any reference to "low profile" for these.
Sent back to Coker.

2nd Pass - Bought a set of Dunlop K81's that were supposed to be the original size from J&P. These came in 1 1/4 inch lower than stock too! Again, no "low profile" reference in the ad.
Sent back to J&P.

Whatdafuck does it take to find the correct tires? Has the 4.10 size been mectrified somehow?

Appreciate any insights!

Think I'll have a beer.

You need a higher profile tire. Maybe a 4.25 width would be taller?

Went to the indy and dug thru their tire info and finally found a cross reference chart that translated the "normal low profile width" to "NOS width"!

Bottom line per the chart is then that a low profile 450 equates to a 400 non low profile.

What fun!

So does that mean that the 4.50 low profile is "supposed" to work?

Yea, the 450 width should work (if you can find anyone making one) per the chart.

Found some Norton forums and see where everyone is going with a 100/90X19 tire (which is available).

Kemp British bikes in Minnesota has $135 tires that are supposed to fit.

Tom, did you get the mirrors? And will they work for what you need?

Got the mirrors but the right side wouldn't clear the master cylinder. Got a set from Drag Specialties that seem to work.

Feel free to donate them to another rider, I have no need for them. No chrome for this guy.
