Silca are making Gravel tyres plus a road tyre. A lot of fluff in there,
note that Maxxis do produce carbon beaded tyres so are others doing it, IrCOm unconvinced itrCOs just a slight cost as to why!

Likewise you donrCOt get something for nothing, and fast compounds tend to be sketchy as, as soon as itrCOs damp, compound really matters, likewise paper thin sidewalls rip easily.

There comparison tyres are both fairly narrow application the thunderburt particularly so, being notoriously bad at well anything that isnrCOt a
straight line, or changing direction ie is fast but braking hard or asking
it to hang in there if your pushing on in a corner just isnrCOt itrCOs thing! The RaceKing is bit more able but itrCOs still an old school XC tyre so dry
and well maintained trails are what its happy with.

IrCOm comfortable old enough to remember old school XC mud tyres which were narrow 1.7/9 inches wide big well spaced nobs and hard compounds and high pressures due to said low volume, on wet clay fields yup brilliant, but add
in wet roots/rocks and mulch and they where lethal.

I think Silca have only though and tested for one use case, and IrCOd expect them to behave poorly once not in that application, I would expect them to
be good on Gravel roads but then itrCOs a fairly high grip environment, with wide space to make any turns, itrCOs a hoot but itrCOs not remotely demanding on onerCOs tyres.

Start weaving through the single track with roots and so on, and I expect
them to perform poorly. Over the years riding gravel bikes IrCOve moved to tyres with grip as there focus, you loose very little in speed even on the road, itrCOs frankly at my level unmeasurable, but they will hang on in there far better, still long way from the MTB tyres I use which are comfortable another level again.

I got that email ad too. Id love to buy a set and try them out, but I
quite literally have enough spare tires right now in my basement to last
me the rest of my life.

Maybe.
We cannot know the hour nor the day.

More topically, tires age. I regularly toss hundreds of
dollars worth of aged-out tires here.

More topically, tires age. I regularly toss hundreds of dollars worth of

I've noticed of late that tubeless tires that have had sealant left in
them too long tend to stiffen up for some reason. I did toss a couple of otherwise good tires for that reason this past spring.

I was told by someone at the bike shop that wasnrCOt good to leave the
sealant on the tyre dry. Though I tend to not swap tyres about.

I presently have my two leisure bikes ie MTB/Gravel bikes tubeless and my utility bikes tubed, as those need tyres to cope with glass and so on!

IrCOd also though be interested to try the Silca Gravel tyres out, probably
the 3/4 as the 1 I have used very low profile nob tyres In the past and didnrCOt work for me, ie seem barely any faster but lacking in bite. They are at least in for UK pricing -u99 plus shipping vs -u70/80 getting other brands top end tyres at the local bike shop and almost double what one can get if searchrCOs for deals online.
