Long story short, I was having a go at Kyle and Jackie O's Cruze Car Challenge today and ended up in my car at clareville where a couple of girls in a BMW 1 Series came and blocked the road, I spun a quick U turn but got a bit overzealous and hit a gutter. Silly and completely my fault but all in the name of fun!
It took a chunk out of my sidewall as well and I was worried i'd punctured it, but everything seems Kosher now, pressures haven't changed and it looks mostly superficial.
Lucky for me it's the same wheel that already had gutter rash, it's the unlucky one but thankfully, the only one that this has happened to.
Got it back, wheel looks good as new. Can't pick where the damage was before. Cost $180 so I wouldn't want to do it too regularly but they certainly did a good job.
