Tyres arrived today.

I was supposed to sign for them but at 7:30am in the morning. I think the courier knocked on the door (I didn't hear), no answer so they got left on our front porch.

The GT tyre seems to be a little more solidly built than the basic BT-23, The front tread pattern is different as well. I think the rear is the same but I need to check.

At 10 am this morning I started the wheel removal (plenty of dog supervision as well) and took a few photos as I went. The A model, compared to the standard model has a little extra work involved getting the wheel off.

Will post up in the next day or so after it's all back together.

And the tread comparison between the GT tyre on the left and the upside down standard 23 on the left.

The rear wheel has just been changed over to a 1300 rear T30 GT spec with the front one booked in for a tyre change at the car tyre dealer next Wednesday.

Looking at the mileage the previous BT-023 GT Spec 1300 rear gave me 9581kms which is about 1500km better than the standard 1100 BT23 Rear. The GT tyre had an all but 500km return ride to Adelaide in the wet with no issue at highway speeds or in city traffic. As usual the softer side tread compound wore quicker than the harder centre compound so I'll be watching this on the T30 tyre.

The drive flange when removed had plenty of moly paste unlike the first post back in 2011 and more was added this time around.

Rear brake pads down to about 1/4 pad thickness left so after front pad inspection next week I can decide to either do pad change over/fluid when they arrive or wait until next oil change (in 5000kms) and do clutch and brake fluid at same time.

I even managed to clean the wheel before putting it back in place.

This reminds me that I have a few sets of the o rings for the rear wheel that I don't think I will use given that the ST won't be doing near as much distance for the forseeable future. So if anyone needs any let me know.

If you bring them to Uralla we can do a deal on at least one set.

saaz · « **Reply #29 on:** July 02, 2014, 07:59:16 PM »

Ok, I will try and remember to bring them.

Front tyre is in the process of getting swapped over to the new Bridgestone T30 GT with expected refitting of wheel tomorrow and a ride to Port Pirie on Thursday.

After 10650 km there's still a couple thousand k left so this is the first time in a while that both tyres have essentially been replaced together. Though a week apart I've only ridden 11 k in the last week down to the shop and for fuel.

Wear on the front BT 23 GT has been almost even across the width of the tread unlike the standard BT 23 which had more wear in the softer compound each side of the centre tread. The new T30 is only a single compound tyre on the front so it looks like old is new again.

The front RH inner brake pad is the most worn and below 1/4 remaining so pad change will take place before then end of the month when I get a drain hose and more brake fluid for the overdue fluid change. This time I left the LH calliper in place (usually remove) and it's now a little less work in removing the front wheel.

saaz,

if you've got another set of 'O's I'll do a deal n take em at Uralla also

I will grab them now and pack them in case I forget! Abe got them, but I forgot what they cost, will have a look back at PMs.

There are 5 sets in the packet, was $16 for the lot, so I will divide them up for those who want some.

John,

Can you keep me a set as well for my next tyre change.

We're still deciding about this years border ride and if we don't go we can meet along your route up near where we live and collect them. Any idea of your route south of Port Augusta yet?

Abe · « **Reply #34 on:** July 09, 2014, 12:52:30 PM »

Here's the link:-

2 of the three rings fit the 1300 and Goldwings (some)

May be time for someone to do a group buy.

So much for refitting the wheel yesterday as it was to cold, rainy and windy. Needless to say that todays ride to Port Pirie was delayed a couple days. The skies cleared a little so wheel refitted this afternoon.

Still using Dyna Beads so all that remains is to put some air in the front tyre before I go anywhere. I'm still unable to say whether over the last two sets of tyres they've done anything or not but they don't seem to do any harm either. So until I'm able to get wheels/tyres balanced the beads will still be used.

alans1100 · « **Reply #37 on:** July 21, 2014, 07:26:23 PM »

On Thursday the tyres had their first run at highway speeds and with the trailer in tow. Being aware of new tyres the ride was a more casual pace of around 90 - 100 k/h and on dry roads.

The newer T30 GT tyres seem firmer than the BT 23 GT but if that makes any difference to tyre life remains to be seen.

Added weight in the trailer for the return trip, slightly cooler temps in the late afternoon plus a couple downhill runs in excess of 110 k/h (state limit) so a mixed bag on the way home with new tyres now ready for normal usage.

alans1100 · « **Reply #38 on:** November 19, 2014, 05:05:53 PM »

Here's an update on the Bridgestone T30 tyres.

No wet weather riding at the moment other than a ride or two down to the shop. Roads in my area would be 80 percent straight which is reflected in the rear tyre wear. About half the distance is with the trailer and 95 percent would riding two up.

Since they've been fitted I've only done 3650k and the front showing very little wear but it's even across the single compound tread width though the angle of the sun light suggests otherwise.

The rear is just beginning to square off on the RH side where the two compounds meet. As above, the angle of the sunlight makes it look worse.

alans1100 · « **Reply #39 on:** March 15, 2015, 11:24:53 AM »

After just under 9000 km the rear tyre has gone past the legal tread limit. In that regard it's no better or worse than the previous BT-23 GT that was on before.

The front has more even wear and a few more km's to go. As with the rear more wear is evident on the LH side of the tyre.

Bang goes "the camber causes uneven wear" theory (unless you ride on the right side of the road around Peterborough).

alans1100 · « **Reply #41 on:** March 15, 2015, 01:18:16 PM »

That wear may have something to do with lean angle.........Perhaps I'm more confident when doing a LH bend than I am doing a right.....my corner speed is also faster on the LH than the RH which would cause the LH to wear a little quicker.......both reasons sound good so they'll have to do.

I got rid of them all not long after.

With the recent disgusting downward slide of our dollar I bought my new tyres from the local car dealer. The rear 160/70 T30r (not GT spec) was fitted a in March for $283.95. The previous GT spec tyre was a few k's short of 9000.

The front (not GT spec) is getting fitted on Friday with the current GT spec tyre having done 12,200 km.

I don't see any of the advertised improvement in tyre range of the T30r GT spec tyre over the BT23 GT spec tyre nor is it any worse. The front tyre will cost us $230 fitted.

I ordered these tyre balancing beads today and to my door for just over $26. http://www.ebay.com.au/itm/200953853375?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT.

Good as place as any to put this.

The last time I checked air pressures on this set of tyres was the eve of the Border Ride in August so about 5 weeks ago and I haven't ridden to far since then. This afternoon I checked them and to my surprise the pressure hadn't dropped at all. All good for a ride to Port Pirie tomorrow now.

alans1100 · « **Reply #46 on:** February 10, 2016, 12:13:26 PM »

Rear tyre replaced today with a PR3 170/60ZR17 (1300 size) with the just removed Bridgestone T30r making only 7018Kms. To be fair though the first 2000 km was a two up trailer trip to last years border ride and about half of the remaining kms was with trailer as well. Hoping the PR3 gets a lot better than that.

With the car off the road due to a faulty steering lock (needs new column) the wheel and tyre was picked up at 7:30 this morning (guy on way to work) and has just been dropped of on his lunch break. Country town service and he also put the balancing beads in the tyre; they do it for trucks so they're used to it.

alans1100 · « **Reply #47 on:** April 20, 2016, 10:01:08 AM »

The front wheel is down at the tyre place getting the T30 Bridgestone removed after 11450 km. Not yet down to the wear bars but I noticed a slight crack in centre of tread so being the brave soul that I am and not wishing to tempt fate with a Whyalla trip on Saturday so the PR3 is going on today.

The PR3 rear after 3800 km seems to be doing a lot better than the T30 it replaced for the same distance.

. Gidday Alan.
I was wondering that when you change the rear tyre ,160/70 to a 170/60 series is there a noticeable difference in a higher rpm at highway speeds? Being a lower profile.Good write up about your tyre history .

Brock · « **Reply #49 on:** September 03, 2016, 12:05:38 PM »

John,

There is no noticeable difference in RPM, or drop in range or increase in fuel required for a distance
