I think the 145/70-6 (DB OEM size) is about the largest 6" tire you're going to find. The Carlisle Straight Rib tire above is 14.44" OD mounted and inflated per Carlisle's spec sheet. That's close to the OD of a typical 145/70-6, the 15x6-6 rib tire is probably a bit wider than a typical 145/70-6. Being a L&G tire, it's engineered for use on grass and dirt at speeds below 10 mph. Carlisle used to have a statement on their website stating that all of their L&G tires were for 10 mph maximum speed. Now it just states that all of their L&G tires are NHS (Non-Highway Service) which basically means they are not to be used on pavement (likely due to rubber compound and construction used). I would not recommend any L&G tire for use on a minibike unless it's only going to be used for putting around the yard below 20 mph.

You didn't state your intended use of the tires. For a large OD tire to be used mainly on pavement, I would suggest this 15x5-6 tire sold by GPS (I haven't seen it elsewhere) but is currently out of stock (like many imported items, due largely to COVID-19).

For an very aggressive off-road tire, I would suggest this SunF tire in size 145/70-6 (DB OEM size).

Those are two extremes in tread design, there are plenty of 145/70-6 chevron (V), lug and knobby tread tires in between. The size, 145/70-6, indicates a section width of 145mm (5.71"), aspect ratio of 70% (sidewall height from bead relative to section width) and the 6 obviously indicates it's for a 6" diameter (at bead) wheel. 145x.70=101.5x2=203 203mm=7.99" 7.99+6=13.99, so call it 14" OD. That's the formula but actual OD and width can vary quite a bit from one tire to another. Again, I doubt you will find much of anything that's larger than the 145/70-6.

I love those tires. Grabbed up an extra pair of them a month or two ago when they were last available.

Studz also sells them, but is currently out of stock as well. http://www.studzracing.com/product-p/kd1556str.htm

Just noticed Studz did steal pics from GPS. I've ordered from Studz multiple times with no issues.

edit: Here's a pic of my CT200U that's running a Doodlebug rear wheel with one of the "ultimate mini bike" tires on it.

15x5.00x6 fit without having to offset the disc and caliper. I wanted 15x6.00x6s to fit soooo bad. Pacnorwest on YouTube has one with them but I think he used a different caliper, JanticJournal used a mb80 caliper. I also noted that multiple doodles come with slightly different discs. I have a DB30S and a DB Racer, they both take the sane hydraulic disc calipers but the offset is slightly different. I'm going to be reading this thread carefully because I really want those turf tires. Also, does anyone know where to get the original 145/70/6s? I bought a HiRun from TSC on a whim and it looks more like an AT145/70/6.

Sweet. So I made a good purchase for once! I sold my Trailmaster Storm as a rolling chassis so someone's kid wouldn't kill themselves with the hot 196 on it. Never again will I buy snow blower tires. I kept the stock ones, they are AT145-70-6. Pretty big difference from the standard 145-70-6 but better than nothing i guess. The HiRun looks promising, no dimples in the treads and a "ribbed" looking bead
