Question about tires, Bias vs Radial.

Tire dimensions noted in the registration?
I love your roads over there but I hope their level of their 'concern$' over 'motorcycle $afety' stays on your side of the pond! ;)
I never noticed a big difference between running the 110s and the 120s.
And the ST1300 has the same front tire as the ST1100 ABSII and I have ridden one of those in the Alps.
I guess if you know no better it makes no difference ... :biggrin:

Its all fun and game until an (illegally) modified vehicle suffers fatal failure, causing its operator to loose control and crash into you, wrecking your mount/vehicle and/or injure you and yours... or worse... like crashing into a bus-stop fully of kids...
One can have technical amendments done, but such requires a release by the vehicle importer/MFG, be installed by a certified workshop and go through an additional tech inspection by the DMV which, if approved, issues an addendum to your registration... for a noticeable fee of course... and such individual permits always impact ability to sell/decrease prices...

No such thing like bolting a supercharged big-block into a Ford T chassis with wire operated drum brakes and drive that through the city...

Slapping a bloody car tire on a motorcycle, not happening... (unless its a permanent side-car, which makes it a two-track vehicle anyway...)

Ah, same for automobiles? Tire size locked into on the registration?

Well, to that extreme I will give you that point.
But back to the discussion, putting a 120 rim on a standard ST1100 is a far stretch from bolting a supercharged big-block into a Model T chassis. ;)
Why back in the day, I helped install a Ford 350 V8 in a Triumph TR something or other....

As given by the MFG, often like 2~3 dimensions entered, which bear no technical issues (like rubbing in the wheel wells, overloading bearings & suspension joints, etc...)

Which original 2.2ltr engine offered like 100HP, propelling it to a Vmax of 108mph...
Alone the weight shift by installing that 6.7ltr V8, the overload on the frame, tranny line and suspension/axles...

As a general rule of thumb must brakes have 4 times the power of the engine installed...
One can confirm by comparing the distance it takes to reach i.e. 80mph to the distance when hammering the brakes from that to zero...

Until some nifty lawyer finds an expertise stating that this modification might have impacted the handling, hence might have contributed to the incident in question, and from there the case grows legs and starts to walk around...

Well, the US is the Land of Litigation, and somehow there are modified vehicles everywhere. Statistically speaking, if it was a problem, they'd try to regulate it more than they already do. Which apparently isn't much at all compared to where you are. Which is fine by me, I wouldn't last an hour with European rules. I find the US confining enough....

Mind your lower speed limits (which are heavily enforced IIRC), the broader (= dull) road architecture and possible lobbying by the car & oil industry...
I'd likely fall asleep at 55mph/88kph on rural roads, more used to our 62mph/100kph, or the 80mph/130kph on ze Autobahn...
And despite this a W speed index is mandatory on my ST's tires... simply because the bike is technically capable of >240kph/150mph...
Higher speeds, narrower roads, tighter bends, etc... cause more stress on vehicles/suspension, whilst requiring appropriate reliability...
I recall that US semis/HGVs cannot be registered in Europe over too weak brake systems...

And what I can observe (and fear) over the years, is the tendency of dulling (and dumb down) all and everything to "murrica levels" over here...
Things like "do not attempt to dry pets in the microwave" or "warning, content may be hot" on coffee cups... dafuq... :unsure:

I didn't say it was smart, but my help was requested so I helped. ;)
They actually got it running but they did not take in consideration the smaller size radiator on (IIRC) the TR6.
I don't know if they ever resolved the cooling issue or not.

As far as lawyers go, they will follow the money just like a shark follows the blood.
And if they go swimming in a shark infested area, the sharks will leave them alone because of professional courtesy ... :biggrin:
 
And here is the killer, Bridgestone themself still list the Exedra:

Result | Model | Motorcycle Tires | Bridgestone Corporation

Bridgestone Corporation is the world's largest tire and rubber company. In addition to tires, Bridgestone manufactures diversified products, which include industrial rubber and chemical products as well as sporting goods.

So why does no dealer carry them?!!

this is usually a regional thing and varies a lot from state-to-state.

In California the typical freeway speed limit is 65 or 70, but most of the traffic is going 80-85 when everything is flowing without any stops.

Some states are strict on giving you maybe 5 over, others are more forgiving. I drove all around Florida last year and people there seemed to be doing 10-15 over, but I don't have a lot of experience in other states recently. I-15 in Utah has speed limits of 80 and even 85 I think, so that's the only place I've actually driven/ridden the speed limit. When I'm riding I stay off the freeways and ride the smaller twisty roads anyway.

Yeah, we all know Europe is superior in all aspects of everything......
 
New tires fitted, took the mechanic a whole of 2 minutes to fit the back tire, no problems what so ever. :)

3 new oring's, and new moly paste on the splines, had a bit of trouble getting the rear wheel fitted again, but a few choice words, and on it went. :)

Well, there restrictions...

the [GT] is only avail in the following dimensions:

front: 120/70 R18 TL 59 W
rear: 170/60 R17 TL 72 W, 180/55 R17 TL 73 W, 190/55 R17 TL 75 W

for my non-ABS
T32 front 110/80 R18 TL 58 W
T32 rear 160/70 R17 TL 73 W
only the "regular" version is offered...
Which bears the question if I'll shred them to pieces within 3000 to 4000 miles... :unsure:
This would ban any regular holiday trips in the future, as I'm not keen on having to plan a pit-stop half way through the trip... :cautious:

I have ridden a season with Michelin Road 6 GT on a K1600 which I was very happy with. I think it would be a good tire on a 1996 and newer ST1100 ABS. Has anyone ridden with similar tires... What would be the best tire size when choosing the Road 6 GT...
