1937Zenith

Look Ma, No Hands!
Just picked up this 1992 dyno detour. Trying to figure out what era GT tires belong on this bike? I believe it’s supposed to have the older tread 1.75” tires but just trying to confirm. Does anyone know what was the transition year where the letter font and size changed? I attached a photo of the ones I think belong. Thanks for any help

Wore out three sets of tires already!
Nice bike! I think you can put on whichever you prefer and be fine. Some go by preference, they like how the bigger tires fill out more. I really wouldn't be too concerned about which is "correct" on this bike. I had a high dollar '87 GT Pro Performer last year and the consensus then was to put whatever on it. I went with some really nice Panaracer HP406s: https://www.ebay.com/itm/254401231955?campid=5335809022

GT recently re-issued some of their heritage tires, pretty cool! Though supply has been spotty or else I would've got some LP5s. Check em out here: https://www.gtbicycles.com/usa_en/goods-gear/bike-parts-components/tires

One more thought - you could try looking for 1992 Dyno catalog scans.
Perfect thanks for the info! That performer you had was gorgeous! Was that original paint? I had an 88 pro performer I sold a few years back before these bikes shot up in price. Kinda wish I held onto it now haha. It was far from perfect but was all original even had the GT block letter stamped chain

Those original gen 2 tires for your Dyno were released around '87 in 1.75 and 2.0 sizes in black or tanwall and were offered in MX or freestyle version. These tires have 1 smaller gt wing logo on them.
The gen 1 version were skinwall and same specs as the gen 2 but had 2 larger GT wing logos on them and these were made in '83-'84.
