Great product. Easy, if time-consuming, to install
These tyre letters are excellent quality and the fitting kit you get is comprehensive and also of high quality. A lot of products of this type skimp on the extras like cleaning solutions and glue but the ones included in this are excellent, which is really key to getting the most out of the product anyway.
The instructions are thorough and the associated videos bring the process to life a bit better as well. I found that following those and taking plenty of time to install, with thorough prep and slow methodical application, gave me a fantastic result.
Despite quite a lot of 'stickers' to apply (long words and additional flares) there was enough acetone cleaner and glue to do all four wheels with a little to spare.
After a week of driving with them, they seem very solid. A couple did begin to lift around the edge after the first drive but I was able to just clean and re-glue those edges and they've been fine ever since. I probably just didn't quite glue to the edges enough the first time on those ones.
Overall I would definitely recommend this product. I'd say to allow plenty of time to install (give yourself an hour per wheel), watch the demo video beforehand, and take the wheels off to do it.
