vtx 1300 c with 200/50-18 .. What size is the correct to darkside?

Hi, I have a VERY custom vtx1300C, with 18" in the rear, currently using 200/50-18, the tire before this was a 180/55-18 , but I am considering (very very much) going darkside ..., I make about 12000 miles a year, which means I am going thru 2 tires a year more or less, and here in South Fl, there are no real curves..

What do you guys recommend?

Thanks in advance..

Welcome
Another new member here just put a 215/45-18. Hancook Ventus V12 evo on his F model.
I don't see why that wouldn't work on your C model.

Sorry you don't have any real curves to enjoy your car tire on, but y'all have a lot of rain showers
and you will love the way it handles in the wet.

I agree the 215/45-18 will be your best match, if a 215 will fit your wheel properly.
If not it will be hard to find an 18" tire, all depending on your set-up.
Good Luck, let us know.
