Tyre pressures? Yes I know it's been done to death

[onearmedbandit]

Have you looked into nitrogen? Talk to your tyre shop, it holds the pressure for ages.

Might give it a whirl, but I think there's only a couple of places in town that supply it. Thanks.

Phil has a bottle and a filler, we use it on the mini motos (because taking a compressor to a car park would be futile).

Recommended pressures for my bike are 41 front and rear. Seems a bit high compared to other sportbikes, but other sportbikes don't weight 215 kg dry either!! I have put 36 front and 38 rear. I have found the softer pressures seem to soak up the small road imperfections and also the ripples on corners caused by trucks which are going to be allowed to carry an exta 9 tonnes per truck! But that's for another day........Having owned an R1 not too disimilar from your Gixxer I'd be putting a sport tyre on the front at 34-36 and a sport touring tyre on the rear at 38 myself. NZ roads are made of that coarse chip that gives loads of grip. You don't need race rubber. My two cents worth.

"I had a front changed and it was somewhat triangular, so I asked the guy why that was and he said it was because i had over-inflated the tyre , but his boss said that was`nt the reason, he said it was because of the camber on the road , which makes sense I suppose so the right hand side of the tyre wears more."

Yep, so true. Have look at these pics. Was confused first how right side could have so much more wear. But after some brain work we came to same conclusion

That's quite fascinating. Is the roads' camber quite pronounced where you llive? You'd also be leaning in to the right side without realising it too.

Check pressures.....hell, about every 6 months if she feels a bit skittish?

No, all straight, wheels in line, bearings good and pressure fine. Bike used mainly to and from work with some minor rides occasional w/e. So the tyres go over same road every day, also through 3 roundabouts a day x 2.

Just tested my tyres today (cold) since its been a good couple of months since i checked them and inflated.

Front was 29.5 and rear was 27. I noticed and felt the rear has been a bit low. But is this dangerously low or bad at all for the tyre?

Obviously im going to go pump them up. Since tyres will be warm thinking 36 front and 40 rear.

Should probably say this is on my gsxr1000k7 with 120/70 and 190/50 with pilot road 2's.

I know all about the 3 degrees from cold to hot but not really too interest if im only 2.5-3.5 degrees warming up.

Should also mention bike is used mainly for going to work and little rides by myself. But also starting to ride 2 up on little rides maybe once a week. So trying to get a good compromise on tyre pressures for single and 2 up riding.. without having to change pressures for each type of ride.

Perhaps 38/42 warm pressures? Whats your views on all this.

Cheers
Anyone have any recommendations for what sort of pressures i should stick around.

I've got a K7 GSXR1000 as well, running Bridgestone BT016. I've mucked around with pressures quite a bit both on the track and on the road. For me (78kg plus leathers) I've found that the track likes 32/36 cold and that suits my riding style, gets a bigger footprint on the ground under braking but still corners well and doesn't shag the shoulders too much, even thoiugh 016's are prone to front shoulders taking a hammering.

On the road riding single I've tried all psorts of pressures and and I reckon that 34/40 is probably about the best. I was running 32/38 but found the front wore too fast although it felt OK.

As for pillion riding, I'd say stick to the Suzuki recommendation at 36/42 and dick around with your suspension rather than the tyre presssure to get a more comfortable or better handling ride.

I adjusted the suspension when i first started riding 2 up as current set up was really soft and horrible. Front is back to factory specs and rear is a bit stiffer than factory now.

Just got around to doing my tyres after work today ended up putting in 36 front and 40 rear (yet to check with my tyre gauge what it actually is). And This is the nicest my bike has ever handled riding by myself. So im definately sticking with around these pressures. Ill hopefully go out for a ride 2 up in the next 2 or 3 days and then judge if maybe i need a couple more pounds in the rear tyre.
