interesting tire size...my Rio5 has the same ones...when i bought new tires last year for it, it was between the Michelin's and General Tires you mentioned...the RT43s are very well rated and were less expensive, so i went with them...they are very good tires and i am quite happy with them...as well, if you get caught in some light snow (before you switch the tires over) they are actually quite good, so just a bit of extra there for you in case you need it...you can't likely go wrong with either, but if you're leaning towards the RT43s (assuming they are less expensive), don't worry about them being "cheap crap"...they are a very good tire (General Tire is part of Continental Tire) and i believe most in here strongly recommend them (i was recommended them when i was looking for them).
