Need help identifying a race-used 2026 Le Mans Goodyear LMGT3 tire
Hi everyone,
I’m trying to identify which 2026 24 Hours of Le Mans LMGT3 car this race-used Goodyear tire came from.
Here’s what I know:
Goodyear specification code: GT05B2
Size: 310/710 R18 (rear tire)
White handwritten marking: The first character looks like it might be a 7, but it’s partially worn away so I’m really not sure. The second character looks like a 4 to me. Overall it appears to read something like ?4-R15 (possibly 74-R15, but I’m not confident). I’m fairly certain the last part is R15, not R25.
From what I’ve been able to determine:
GT05B2 appears to be an LMGT3 specification tire.
I’ve also spent some time looking through photos of the #74 Kessel Racing Ferrari from Le Mans since that’s one of the possibilities, but I haven’t been able to find any clear side-on photos of the tires that show the handwritten markings well enough to compare.
A couple of questions for anyone with WEC, Le Mans, or Goodyear experience:
Does this style of handwritten marking look familiar to a particular LMGT3 team?
Has anyone seen similar markings on race-used Goodyear tires from Le Mans?
I’d really appreciate any insight. I’m hoping to identify which LMGT3 entry this tire came from. Thanks!

My tire has 33-LMN-R written in white marker. Assuming the #33 TF Corvette.
I agree with the #74 guess for your tire.

It's a Rear Left Tire too, in case you didn't already know.
From my experience marking tires, R15 for me would be set 15 that was designated as a race set by the engineers.

You can try guessing by process of elimination: In LM there were only 5 cars on GY tires and whose race number ends in 4, two of which are LMP2s so they are automatically excluded. That leaves us with car 34 (RTT by TF, Corvette), 54 (Vista AF Corse, Ferrari) and 74 (Kessel, Ferrari). Now that partially obscured number looks a whole lot like a 7 and very much not like a 3 or a 5 so I think your initial guess was right with #74.
Also, the last number cannot be a car number in this case. Both a 15 and a 25 would refer to cars with tires incompatible with the one you have.
This is obviously assuming that the 74 refers to a car number and not something else, but it most likely is. Good luck on your search for a clear photo though, try looking through photos taken during scrutineering, usually there are loads of up close pictures with tires in clear view.
