My 08 oil burning Ratblade came brand new with a 190/50 rear tyre. When that gave up the ghost after 7000km I had a lot of trouble sourcing a replacement (I live in the middle east) and had to bring a set (2CT's) in from the USA which cost heaps. This second set is now on the way out.However I can get 190/55's locally. Question: is a 190/55 OK on an 08 Ratblade? Are there any issues I should be aware of? Will I fall off and die?
