Tyre type discription?

[tramp]

Having a senior moment

about to get the rear replaced with a tourance [ cos I like them nuff said]

but noticed their is a huge price difference depending on what type,

ie: 130/80/17 s or 130/80/17 S TL and H rated

now I dont go fast well never over 100mph so S rating should be fine

but as I understand it the "TL" stands for tubeless fitment so as al tranny`s are tubed supose its the S rated only? or can I fit the TL type if available cheaper?

so come on put a old git out his missery, dont trust the tyre shop as they only want a sale.

And anyone put ACF50 on the inside spokes? as I know its corrosive to rubber but surely better than wrotten spokes?

[tramp]

ah Ha!!

the s rated tyre is a crossply, the H rated are Radial.

next question I know the construction is different but what advantages does the radial have over cross ply?

[Mabels Old Man]

radial tire (more properly, a radial-ply tire) A pneumatic tire in which the ply cords extending to beads are laid at approximately right angles to the center line of the tread. it is a particular design of automotive tire in BRITISH ENGLISH tire .The design was originally developed by MICHELIN in 1946.ires are not fabricated just from rubber; they would be far too flexible and weak. Within the rubber are a series of plies of cord that act as reinforcement. All common tires (since at least the 1960s) are made of layers of rubber and cords of polyester, steel, and/or other textile materials. This network of cords that gives the tire strength and shape is called the carcass.

In the past, the fabric was built up on a flat steel drum, with the cords at an angle of about +60 and -60 degrees from the direction of travel, so they criss-crossed over each other. They were called cross-ply or bias ply tires. The plies were turned up around the steel wire beads and the combined tread/sidewall applied. The green (uncured) tire was loaded over a curing bladder and shaped into the mould. This shaping process caused the cords in the tire to assume an S shape from bead to bead. The angle under the tread stretched down to about 36 degrees. This was called the Crown Angle. In the sidewall region the angle was 45 degrees and in the bead it remained at 60 degrees. The low crown angle gave rigidity to support the tread and the high sidewall angle gave comfort.
By comparison, radial tires lay all of the cord plies at 90 degrees to the direction of travel (that is, across the tire from lip to lip). This design avoids having the plies rub against each other as the tire flexes, reducing the rolling friction of the tire. This allows vehicles with radial tires to achieve better fuel economy than vehicles with bias-ply tires. It also accounts for the slightly "low on air" (bulging) look that radial tire sidewalls have, especially when compared to bias-ply tires.

There you go

So, which is better?

[tramp]

well thanks I am now another informed punter

called me local tyre fitter and got a price of £102 fitted and balanced with new inner tube and he takes the wheel out and replaces as well.

so no dirty mits , he said the crossply were for mainly light smaller bikes [well that counts the alp out] and as I tour with the full kitchen sink he said it had to be the steel belted Radial as they carry more weight at a cooler tyre temp [so no exploding].

so getting a Tourance 130/80/17 s rated radial apparently £20 cheaper than the h rated , well I dont go that fast as only Birds are made to fly.

The difference is that the tubeless / radials have stiffer side walls

This translates to marginally better handling as they don't deform as much (especially noticeable on front tyre) but not so good if you change your own tyres 'cause they are hard to break the bead, remove and fit

[Treadtrader]

Tubeless tyres with tube, no problem. Best with matching manufacturers tube.
Make sure the tube they fit is'nt some cheapy from China.

Radial is the better fitment, modern technology.

"S" and "H" is'nt just a speed rating but an overall perfomance rating. "H" for instance gives better grip and braking but may wear quicker.

Lastly insurance companies know what should be fitted, any non-standard fitment can cause claim problems, any excuse not to pay out.
