Tyres Bias or radial what do you use

[Superjack44]

The Bridgestone Battlax BT45's on my superfour are done for what tyres would be best to replace them with I want touring tyres that give good mileage .
The tyre sizes on the bike are
Rear 150 70 17
Front 110 70 17
I think the rear could be the wrong size so what is the correct fitting.
Having said that it was a joy to ride in the twisties

Original tyre size rear is 140/70.
I have a bt003rs on rear, gives loads of grip and feel, but won't last long. Is mighty good fun though

[superfourben]

Correct size is 110 70 17 on the front
140 70 17 on the rear

BT45's are good long lasting tyres, have had them for ages
BT 090's are fantastic but don't expect more than 4000kms out of them, no good if you are commuting

I ride Pirelli Sport Demon Bias tyres. They are really comfortable to ride and have pretty good stick for a sporty commuter tyre. Not sure how long they will last. I put just over 10,000 on my Shinko tyres. They were really good for commuting and cheap as. They were pretty hard though so they didn't offer the same comfort or stick as the Sport Demons (although surprisingly good in the corners despite the rather hard compound - good enough for some twisties and tons of urban nuttiness). I have heard though that some riders get near 10,000 on their Sport Demons...here's hoping.

I would be really keen to get some Pirelli Angel or Michelin Pilot Roads2 (dual compound tyre) as radials can last a lot longer than bias tyres while offering better handling at the same time. They are mighty pricey though and loaded with technology for much faster and heavier bikes...a little over kill on the CB400. Might be worth it though. A dual compound radial tyre could last a really long time while still giving you loads of stick in the corners. Although the Pilot Active (urban bias tyre) is claimed to be as durable as the Pilot Road 2 of course with a real reduction in grip. The hard compounds in bias tyres designed to last a long time can make up for the performance lost because they aren't radials with softer compounds. Kind of a balancing act. Hard bias tyre = cheap long lasting with less grip or Soft radial tyre = expensive long lasting with much more grip.

Other tyres are the Michelin Macadam 100 (20% less durable than the Pilot Activ with more stick) or the Metzler Lasertec which have a reputation for being really good in wet conditions. Some reviewers have claimed they are way better than the BT 45s however there seems to be some worry about their longevity because they have a lower tread depth...although they are said to resist squaring more than the Bridgestones so they handle better for longer...
