I'm thinking to replace with my stock 18'rim with 19' Volk TE37.
Along with this, I need to change my tires too.

What do you think about Kumho Tires?
Another altenatives are Toyo's but little bit expensive.(yeah.. out of my budget after replacing rims )

Your comments will be appreciated

 

Which Kumho tires are you looking at...street or competition? For the street the only really good Kumho is the Ecsta MX. The MX is a big improvement over the Ecsta 712.
