Hi guys and gals,
I'm going to put some new tyres on my 1300 and found some bridgstone battlax sports touring t30f...
Anyone know anything about these? any good?
Cheers Dean

Most find them a bit poor wearing, the best choice for wear and handling are the Michy PR4 GT.

I have those but with my limited experience I would only say they would be better than PR4s if they were a lot cheaper.

Ok i think they quoted me 210 for the front and 300 for the rear.
I haven't looked elsewhere as yet so not sure if this price is ok but they have them on the shelf

I've just used a rear T30 Evo and managed 9000km but that's with mostly two up and some trailer usage included. It's on par with the T30R and BT23s I have had before.
I got my Dunlop Roadsmart tyres from here. In most cases they are freight free except for NT, QLD and WA

The last Metzeler I used was bad, made a vibration for some reason, like riding over a cattle grate... and I wouldn't use PR4's ever... I use the Conti's, Road Attack 2 EVO's on my other bike, he best tyre I've ever used... not cheap, but given me more confidence than any other tyre I've ever had... but they also aren't cheap....

Can you expand on that statement, I use PR4s on the 100, and they are the best I have tried. (cant get Metzlers in the right size any more)

The rear PR4's aren't too bad but the front tyres are shocking... they don't wear well, and when they reach around 50% you need to remove them... I see so many of them in my workshop, major handling problems due to uneven wear... I don't like the tread pattern at all... I currently have one on the front of my ST1300 which I'm going to replace soon... when it was new, was ok, but now it's wearing, the bike is difficult to handle, I usually run 42psi, find its better with 45...

Initial grip was fantastic but I only had 8000K on them and will not use them again
As for the PR4 I have them on at the moment and have no issues with them (touch wood) have only heard of two people so far that have had a poor experience (both of them on the forum)
Have done a lot of Km on the Angel GT around 22000Km.

I have just had another set of PR4's put on the :blu13.
I agree that they do last longer with a higher pressure.
I find 44psi front & rear is good but checking the pressures regularly is the key as the
front does wear appallingly badly/unevenly if you don't check it weekly.
I got 12 months out of the last set.

How many k`s out of the front before its apparent there is an issue? Nigel :wht11

Somewhere around 15,000 i reckon Nigel - but i was very lax at times checking the pressures.The front had started going funny on one side around mid january.
It was only a nail in the rear that made a new set a fait accompli earlier than my wallet had planned.

OK, so 15k is pretty good, just need to monitor pressures, that seems to be the answer! I currently run Angel`s, just trying to get a comparison. Thanks Nigel :wht11

Just my 2 bobs worth and my comments apply to the 1300, tyre pressures are important and critical to tyre wear. My tyre supplier finally convinced me to run higher pressures for Mich. PR4 F&R and as I run a tyre pressure monitoring system was able to confirm that what he suggestions were valid. At 42psi cold with 30 degrees ambient temp, the rear pressure would rise to 55-56 psi at 100KPH. At 47psi cold the pressure would rise to 54-55 under the same conditions, i.e. a lower running pressure. The result of this is less wear due to the lower temperature that the tyre is running at as pressure rise and temperature are directly related. The first PR4 (42 psi cold) lasted just over 8,000 K with most of the wear being the right side edge with lots of 'bearding'. The second PR4 (47psi cold) is at the 9000 K point with an estimated 30% life left. My riding habits have not changed, love that flat torque out of corners.
There are other factors that come into tyre wear, one of them being suspension setup. Rear suspension settings affect the performance/handling and front tyre wear. As well as checking tyre pressures on each ride and during the ride, I checked suspension setting, in particular, preload on the rear. Also use tyres that conform to the specs required for this bike, both in sizing and importantly load ratings. Remember that the weight on the tyres is not just the weight of the bike, rider, passenger, load and in some cases trailer ball weight. Those that undertake flying know that at a 60 degree bank, 2G is applied to the aircraft and it contents. When turning on a bike is no different and effectively starts to increase from 30 degrees upwards. This is taken by the tyres at an angle which produces tyre distortion, further increasing contact pressure/temperature.
I was iffy at first in increasing tyres pressures beyond the book value but tyre technologies have improved in the 18+ plus years since the design of the 1300 and 27+ years for the 1100 and monitoring has confirmed that the lower running pressures/temperatures=longer tyre life. BTW ride comfort has not changed significantly and ride handling is better if the suspension setup is correct. I know now if the setup is wrong as it does not feel right.

I think you're spot on Trevor !!
What sort of tyre monitoring do you use, and is it something that I can adapt to my bikes ?
It's hard to believe 27 years since the 1100 first release...

I am now using monitoring as part of the Garmin GPS. Previously I had the Doran system but replacement sensors are expensive when the battery is depleted some 12-14 months depending on use. Batteries can be replaced in the Garmin system.
Regarding the release date, design occurs well before this time in most cases, so design specs will have been set before the release making the 1100 design some 30+ years, particularly as it was one of a first in this category.
