Is it worth just changing the rear tyre ? - SV650.org

steveg · 04-01-07, 07:52 PM

Have done just over 4k on my pirelli diablos , rear is about finished ( approx 1.6mm left) , the front has approx 2 - 2.5 mm left .

Do you recon its worth just replacing the rear , otherwise I was thinking of getting a pair of Road attacks

You should use 2 rears to 1 front but that also depends on how soft your tyres are and how hard you ride!

You didnt like the Diablos?? Was this as they didnt last long or you just want to change. Try another on the rear (Corsa

) .

Yes it's normal to "average" two rears to one front when talking of wear. Some people will tell you not to mix and match but I have always done that. So long as you make sure that the front is of a softer compound than the rear you will not go far wrong.

I loved the diablos , probably the favourite tyres that I have ever used , have used them on my last 3 bikes .
This time of the year can't really use the grip that they offer.

Thinking of the Conti's for the winter.

I'm guessing I will pay a ton for a rear diablo , where as i can get a pair of RA for 150.

Just out of interest how much tread depth do you recon Diablos come with when new ?

I would guess front 4 mm? / rear 6mm ?

I mix tyres pretty much freely, there's a lot said on the subject but my own experience has always been fine, and I've tried allsorts... But it's a matter of personal taste, maybe.

You could try a Diablo Strada rear, it'd be a fair match to the Strada front- I ran Sportec/Roadtec for a while which is very similiar, and it worked a charm. I doubt you'll feel much of a loss with the less sporty rear tbh, I certainly didn't when i binned the rear sportec for the roadtec, or when I swapped the front to one either.

Mixing is fine so long as you know what you're doing and keep an eye on the tread depth on the front. If you aim for two rears to one front you could find that you're getting very low on the front to try and achieve that aim. And if you have to change the front a little before the 2nd rear is done, it's not fun with a new, not-yet-scrubbed-in front tyre with a scrubbed in rear.

You don't want the front to have less grip than the rear, or else it'll probably be the front that goes instead of the rear when it gets slippery, and that's harder to save. Also remember that the front does extra work in displacing water from the road (on some tyres like the Z6/Diablo Strada it's even more important as there's no central tread on the rear tyre) and if you have low tread on the front tyre then it can make the rear tyre work harder in the wet than it would normally have to.

I get them both changed at the same time because I can't be bothered checking and worrying about all of that. Some of that is down to how easy it is gfor me to get them changed - if I had better access to a better local tyre dealer I'd probably try to get more life out of the front before changing it.

I change tyres whenever the guy who services it says I'm getting pretty low. But then, I have my bike serviced more than I change my pants, I really should do the latter more often

After the stock 220's I was riding with a front 220 & rear Z6 for a few thousand, which was fine. Then the front let go mid corner

But that was just because I wasn't watching the tread level, and winter was kicking in.

Now I'm on Z6 front & rear & the rear is starting to look like it needs a trip to the shop.
