Tyre Pressures

Post  Truck bandit on Thu 19 Dec 2013, 1:37 pm

Just a quick one, what cold tyre pressures does everyone run and are they touring or sports tyres?

It's something I have a general idea about but always seem to overlook and i'd like to learn more about pressures and the effect it has on tyre life and performance.

38 front 40 rear (42 if loaded) PR2 on both bikes.
If I know I'll be hunting the Bandit through the hills and the front is between 36 and 38 Im happy with that.
You'll know if the front pressure is to low as it will start to run wide when pushing on.

PR2s 36f...42r  
depends on your weight & riding style / suspension set up  though , a lot of others on another forum lower their pressures to get some ....spirited riding in , but then wear becomes an issue  Very Happy

That puts my current shagged 12,000k rear to shame Sad

Do you weigh 6.5kg and traven at 25km/h mate?

no 6 kg actually and i hav'nt gone that fast yet lol! 

thats all sorts of riding, not sure its because i only do long trips or that i check my pressure most days on the trip, i do ride easy but also on occasions go  stupid in the twisties, there are some good roads around mid north coast, Oxley hwy and bylong valley way where you can really test out the grip till you have a moment and slow down,

Damn. I got about 15,000 out of my rear PR2 and only about 8,000 out of the front PR2. Front started to scallop after 5,000 k's. Too many straight roads over here Sad.

Yep and I got 16k out of the last set.
I've documented my frustration on here before about the 20% reduction in this set.
I'd love to see a set at 26,000. Not saying it cant be done......................................
I'm doing 40km every time my bikes are started these days so each of my rides is a "trip".
For what its worth the Power Pures did almost the same distance on the FZ1 and trust me those tyres were pushed pretty hard.
I reckon I got a dud pair of PR2's this time around Sad

I don't mean to doubt you, but what sort of condition was your tyre in when you decided that replacement was necessary at 32000 km?
I'm intrigued at the claimed km of many kn this forum.  
Are you running the things until they burst? Wear markers disappear?  Strings start to wear away? 
Ok. A bit sarcastic and tongue in cheek, but I'm in a habit of replacement when I don't think that the tyre is able to do the job it's designed to do. That is, grip the road in the dry and in the wet. 
If my tyre is scalloped badly I don't have much confidence in it in the wet. 
Personally,  anything over seven thousand km is a bonus.  Most of my bikes have been more sporting than cruise ships but I really worry that guys are putting themselves and those that they ride with at risk by running on worn tyres.

I have to agree with you to a point. I'm on my 3rd. set of tyres in 15,000km. on my FA. The last set were Dunlop Roadsmarts (front 4,856km. rear 5,041km.) and they were worn out on the sides more than the middle. (The bike made me do it Officer!) Even my old CBR1000f gave better tyre life. Same roads, same type riding, same conditions, same old fart riding.
I'm now trying PR3s at 36 front & 42 rear (as per owners manual) after reading the good reports on this forum.

tyre in the middle was worn down to the markers and slightly further, tread on the sides was just to the markers, i dont ride on worn out dangerous tyres, have never had a flat in 20 years of riding, look at my bike, my girl friend calls me ANAL they way i look after it, change my oil AND filter every 5000ks, and use NGK CR7EIX plugs cost alot more but last longer,  changed my original tyres from new at 7100ks could not believe how fast they wore out, put on PR2's changed rear at 33,200ks and then front at 38,800ks have now done just over 50,000 on the clock so the rear PR3 has done 16,700ks and still good, maybe it just my riding style, i guess an indication would be my fuel consumption, easily get 380ks before im looking for a servo, have pushed it to 410ks, last marker on fuel gauge flashing, on my way home hoping i wasnt going to run out, my rear sprocked makes a big difference to that, another indication, on my way over to perth i spent more time on the wrong side of the road (when safe) so i would'nt wear out the right side of my tyre to much, when i got home the left side was actualy worn slightly more than the right

Just replaced a front PR2 for a PR3 today, 10,600 and six months out of the front about  2mm tread depth through the centre, scalloped about 25mm off centre line either side, beyond that near new to the outer edge. Commute to work and back and ride hwy a few times, bike hardly ever sees corners :(38psi. Rear at 42 and still has a thousand or so left in it. Have a PR3 to replace it when ready too.

Same as most of the others - 38 front/42 rear.

I consider myself lucky if I get 15,000 from a rear and 20,000 from a front.

Pr3's - 38 /42  (about 18k - 20k )
Pilot power - 40/42 (dunno as I have only had them for 2k so far).

if you get a flat areas. lower pressures for a few days down to 30-35psi and ride carefully. that takes the edges off them.
