Pair of TKCs for 800gs: cost

Hi All

I want to shod my 800gs with a pair of TKcs. Local 'come to your house / office " fitter is quoting £240 fitted. Your combined wisdom on whther this is a good price would be appreciated,

Thanks.

Johnboy

 

[rockchunk]

round & black are doing a set for £145 + post £10 if i remember corectly not that hard to fit

 

[elevensies]

if thats for removal of wheels from bike, fitting etc etc then its not so bad, if its on removed wheels, its expensive.

its not too difficult to do yourself if you have at least 2 stuffing great tyre levers.

IIRC it cost about £170 at Essential Rubber in Hackney.

I've seen a tyre being put on with two small lightweight motion pro levers. It's a myth that you need lots of brute force and long heavy tyre levers.

 

[WindyChuffer]

Get them from Round and black, and with the money you have saved buy some tyre levers, a bead breaker (e.g.BeadBrakr from metal mule) and loads of lube. Set aside a couple of hours, be prepared for lots of swearing and do it yourself. And you don't need to balance TKC80's in my experience. Did I mention loads of lube? Loads of it.

 

[sijohnston]

a bead braker? the bottom of the side stand of the 800 is the perfect bead breaker (although I've not used it since I put a base extender on), so all you need is the tyre levers. carefully (so as not to hit the rim itself), drop the bike onto the tyre of the wall, and your bead is broken.

......or sit the wheel inside an old car tyre (to protect the disc) and stand on the tyre wall.

As said - lots of lube, otherwise it's a bastard to do.

Two pairs of hands make the job a lot easier.

Dont forget to slacken off the threaded collar on the valve stem when you inflate the tyre and give it a good waggle for a few minutes to get rid of the air trapped between the inner tube and the tyre casing.
There can be a drop of quite a few 'true' pounds pressure once you've done this.

Just got mine from M&P £157 + £5 delivery (also got a bead breaker for £70)

shameless plug

You could buy the Globeriders instructional DVD (which I happen to be in) on the F800GS which shows you a smart and easy way to change your tires.

It's worth it.

You just missed out, i bought two, fitted to the bike for £150 from Micheldever tyres at the Hogroast last weekend

TKC dilemma / speedometer error

Yet another tire dilemma. The Canadian distributor appears not to stock the 140/80-17 size in TKC80 for the F650/800GS bikes. I can apparently have a 130/80-17 which has a lower load rating but correct circumference or a 150/70-17 which has the correct load rating but will presumably cause an even more optimistic speedometer error.

Any experience from those of you who have mounted the 150/70-17?

With thanks for any advice,

Mike

I can apparently have a 130/80-17 which has a lower load rating but correct circumference or a 150/70-17 which has the correct load rating but will presumably cause an even more optimistic speedometer error.

Let's work this out.....

If the correct sized tyre is a 140/80, it has a nominal sidewall height of 112mm.

The 130/80 has a nominal sidewall height of 104mm and the 150/70 is 105mm. So the 150/70 is actually closer in rolling diameter to the 140/80 than the 130/80. The 150/70 has a diameter some 14mm smaller than the 140/80 and therefore has a rolling cirumference some 44mm smaller so it will make the speedo read a bit more optimistically. A 150/75-17 would be just about identical in rolling circumference but I suspect that they don't make those.

If you must choose between the 130/80 and the 150/70, the latter is the better option, assuming that it doesn't foul the swingarm.

£37.79! I would think that's bloody expensive for a DVD :S

Worth a try

Thanks for the help with the math ... The current tire has a diameter of about 65cm so the 14mm difference will contribute only about 2% of speedometer optimism. I think it is already more optimistic than that so I will give the 150/70-17 a try.

I just finished a 7,800 km ride down the Rocky Mountains on some Heidenau K60s. They took me safely through every kind of terrain out there. Here's the report I promised:

tyre changing

i would recomend learning the skill of tyre changing yourself, its not that hard and saves waiting for a recovery in the event of a puncture. oh and yes i agree lots of lube

 

[PRAETORIAN]

Would Metzeler Karoo T's fit on an F800GS? Do they have reduced speed ratings? I would want something that is road biased but better off-road than the stock tyres. But at the same time I dont want to have to worry about breaking a ton because my tyres might pop!

Any help appreciated
