Shinko 805. What does the collective know?

Sitting at 2500 miles on the rear (running a TKC80 on the front).


New



Sitting at about 8/32” tread depth on the center lugs at 2,500 miles.



I never checked the factory tread depth so I’m not 100% sure how to gauge the tread wear at this point. Probably an 80/20 mix of street/dirt.

Very impressed with the performance of this tire for the cost. Loaded up on the slab it handles well, and I've had no issues in wet weather. Offroad they’re predictable. I haven’t experienced any unusual side slip or lateral traction issues on dirt roads, only in the sloppy stuff.

I just bought Kenda Big Blocks because they were considerably cheaper than the 805s. Hoping they last a decent while on a 250cc bike. If the mileage sucks I may end up with an 805 on the back eventually.

I am so flipping intrigued.... I just purchased a regroover. The pics you showed were outstanding. Regrooving could transform the 805 into a legit off-road tire, regardless of conditions.

I'm smart enough to understand that paying attention to tread depth and never grooving deeper than that is critical for safety.

I've also got a whole set of tires on my pickup that are 70% worn and I am going to grove them to help with winter/snow traction.

You linked to your personal order details, which we can't view.

the big block is a better tire in my opinion, I have not ran one on a 250cc bike, but on my boxer GS, the big block wins in every category over the 805. ( but they both suck on wet pavement)

... please forgive me if this has been asked too many times already; but during a 2-day BMW Gs offroad course in August the instructors told us not to worry about lowering your pressure. Now, after returning from a 6-day northern half CircumTas 75% on unsealed roads/tracks - I've experienced much improved ride/grip with pressures as low as 24 psi on rear (tkc70). I'm putting on the Shinko 804/805 pair this week. How much lower than 36psi (onroad) have you (or the collective settled on? Thanks for any info.

Considering a 705 for my next tire with significant grooving, until then Jeep tires could find new life haha. #2 blades move quickly without compromising stability

I honestly just run them at street pressure offroad. I may try to lower them but the bike handles well enough to where I haven't bothered yet. 38F/41R

I never change from street pressures when I go off-road, and been on trails as well as some rock climbing with my 1090. I’d rather a wee bit of slippage than denting a rim.

Re: regrooving the rear... for side slip improvement would you not groove them the same way as the original... just add more grooves? just curious...

Nice home bar selection!

I bought this knobby knife and grover.
2 tools in 1 vs a dedicated grover only.

Transformed a 1/2 worn out street tire on my Vstrom into a tire I did part if the COBDR on.
I can adjust the depth and take multiple cuts for more width.

I added life to my 606s on my WR with the knobby knife cutting tip too.

I would use the factory grooves and just cut them deeper and wider from day 1.
Side slide is the problem right, and they just need to be more pronounced.
