Tires Megathread

Recently had IRC GP-1 in size 3.0-17 installed front and rear. Had to fender lift the front. Definitely better than stock IRCs on the trails. On road get a little bit of a hum at higher speeds but nothing terrible. Haven't had an issue power wise but I also regeared my 23 to 13T front 42T rear, so it has plenty of torque in the bottom end. Overall big upgrade compared to stock if you do any trails and offroading. I forget what my local shop charged me for the tires, I think they were around $40/tire, which even if they only last 2k miles is pretty dang cheap. Had no issues reusing 2.5 tubes, Let me know if you have questions, ill try my best to answer.

With my fender lift kit, though not rubbing the stock fender bolts come very close to the GP22 side blocks, and I am sure I've felt and heard a few sticks and rocks DING against them as they get whizzed around.



300円 for four stainless, low-profile, 3mm in-hex M6 x 10 mm machine screws seems to be a reasonable option to generate some more clearance...



The 10mm length too (shorter than OEM style) keeps the tail end from chewing into the shock boot as well.

Hey everyone,
I contacted Shinko today 11/04/2025 to see if they had any plans or thoughts about creating the Shinko SR244 'Golden Boy' in a 2.75-17 size. Gentleman on the phone said they had nothing in the pipeline. I would be curious how many people would be interested in this tire in that size. There really isn't a tread like that available in the 2.75, its either 2.5 or 3.0.
If you would be interested in Shinko SR244 'Golden Boy' in 2.75-17, please like this comment. If I get enough likes I may reach back out to them and see.

Thanks - Tyler

I'll mention that there is a tire with a very similar tread on the market, Vee Rubber VRM-022. It was available through "Parts for Scooters" which has since been acquired by Scooter Works, but right now they only list the 3.00-17 on their site. You might have better odds of asking Scooter Works to import an existing tire in a different size, than get a new tire size made.

I just figured Shinko is a well known quality brand, and they have the sizes around it, wouldn't hurt to see if they could get it made. Can find Shinko's in the States pretty commonly, but if they don't I might go that route, or just get the 241. I like the IRC GP-1 I have on it, but they are also 3.00-17. I'm going to try something else once I wear them down next year.

I would doubt the size of the US (or even, non-Thai) market would justify anyone's volume analysis...
That said, more options would be nice!

Notable as my IRC GP-22s are hardly what I would call 'hard-wearing', as they are already seeing their blocks ablated after just two months' of admittedly hard trail riding.
