tire life '93 K75s

Use my '93 K75s to tow Bunkhouse camper ,therefore mainly straight road and slab riding.Have several BMWs so curvy riding is rare.I've stayed with bias tires for mileage. I'm curious to learn what mileage difference riders who've used both radial and bias have seen?
 
A better question might be - are there any radials that will fit on your rims correctly? People have shoed radials on K75's (I had them on THE K75S - but it had special rims)...

With Metzler Z6's on my old K75S (on K100-4Valve rims, only made one year).. I used to average 6k miles from a set of tires. Not great, not awful. I'm not a super agressive rider (understatement for sure..)

BTW - I added the year/model of your bike to the thread title. Please consider doing that yourself since it tends to attract people who might have something helpful to say to your posting. And in the future - it might help someone else find the thread if they have the same question.
 
I run standard Metzlers on my 75 and 12-15K miles out of them.
Don't know anything about radials.

It's recommended that if your bike is designed to use bias tires, don't use radials. Tire life is a problem. There are so many variables. One around here is road surface. Oiled roads with gravel that's packed down by traffic tend to have a rougher surface and the stones are sharp, so they cause more tire wear. You could try some of the dual compound tires with harder rubber in the center of the tire and see if that gives you better wear.
 
mini-hijack.

actually, from everything i have gleaned on the 'net about them, the newer dual compund tires appear to have the same standard compound in the center, and a softer/stickier compound along the sides. (they re-engineered the sides for greater grip, rather than re-engineering the center for greater tread life).

carry on.
 
I like the Bridgestone BT45, I get 6k on the rear and 12k on the front.

Folks use to rave about the Dunlop radial (including Greg Feeler, I think) that fit the K75, but they went out of production.

Bridgestone is making a nice-looking radial sport-tourer, BT023, but it doesn't come in a rear for the K75. Interesting choice for a new K bike, though.

The only Bridgestone rear 130/80-17 or 140/80-17 is the BT45.
