Evening Gentlemen,
Sorry! Mornin' all!

Ducati 450 uses 2.75 x 18 on the front WM2 rim and 90/90 x 18 on the rear WM3 rim, I was running a 3.00 x 18, but was running onto the sidewall!

Use Michelin City Extras, or Conti Street brands; Dunlop K82's are sticky, but only last ~2,000 miles on the rear, whilst the Michelin and Conti, about 3,000+ miles. The Michelin have relatively pliant sidewalls and can be fitted, with a tube, grip well on greasy roads and even a wee bit of farm track going. However, they will loose grip on mossy strips up the middle of some back lanes up here, I managed to remain upright!

Having used Heidenau tyres, they are rigid in the sidewalls, a swine to mount and unless they are the racing compound, skaty on salty/greasy/leafy roads!

Hence, I don't use them anymore, inspite of the price. As for Chinese tyres ........

I tend to use engine braking , rather than the drum brakes and the old bird is putting out about 35HP and I'm 85Kg (12.5 - 13.0 stone).
Getting somebody else to fit the tyres to the alloy Borranis, using a tyre machine can be expensive at £15 - £20 per wheel, workshop labour rates are now at least £50 an hour, if you can find somebody competent. Hence, I do my own most times.
Tyre suppliers are either Demon Tweeks, or Two Tyres, the latter is my preferred supplier. Very quick, excellent prices and good advice if you are not sure about which manufacturer, type, size that you require, also inflation pressures.
Two_TyresBeware of buying tyres directly from Continental suppliers, prices look very appealing until you are stung, with 20% VAT and import duty and "No, I haven't!"
Another reason for the high prices for tyres is that Ukraine used to be a main supplier of carbon black, a critical ingredient in the rubber mix, and supplies now have to be sourced from elsewhere.
Good health and go canny on your first snow of the year darn sarf! Just a wee touchy of frost up here that finally did for the nasturtiums and we still have fresh strawberries in the polytunnel!
