The Iron Cross product seems like it would be a durable alternative and certainly much less time consuming than painting individual letters and numbers. But EACH tire costs $25. If it looks like hell in real life, well, that's $100 in the toilet. I'm not even sure they could be removed if they did look like crap.
Regardless, I just emailed them to see if they even have the templates for the Goodyears already made.
Go ahead and experiment with the Goodyears, you will want to move into the vastly superior Bridgestones soon anyway.. :lol
