I am about to pick up a set of kosei k1 racings for my del sol
15" rims
my question is this
how wide a tire can I run, and is a 50 sidewall the right size for a sol on a 15"
I was thinking 205/50/15

or 215/50/15

whats the widest tire i can run on a 15" kosei

beeboyee

go 15 195/50 's

but i want a wider profile
will a 205/50/15 be alright?

and as for the del sol
I know there are 2 offsets
a wider one and a narrower one

I want the one that makes the wheels stick out more
gives it almost a rally look
I am not concerned about being able to tuck the tires in the wheel wells

I run 205/50 A032R's on the Kosei's and it works fine. some rubbing under extreme steering angles, otherwise no problems.

I run 205/50x15" Azenis tires on my 15x7" Kosei K1s. Just make sure you get 45mm offset and then get some 2-3mm spacers. Mine were hitting the rear upper control arms, but a 38mm offset would hit the fenderlips.

I have 205/50 15 Hoosier r3s03's on my 5th gen. with K1's(15x7 38mm offset). Work with a little "love" on the flanges. With any other tire, i'm sure they'll be fine. 195's look anemic on the car.

45 mm offset is the one that sticks out a little better??
wider I mean!

Instead of getting those spacers, you can just shave off the edge of the rear upper control arm. I still don't know why Honda didn't do it to all their cars, because there were very tight clearance (2-3mm of room) between the 15x7" 45mm kosei and the rear upper arm of a 99 GSR. But that was not the case when I tried installing it on a 99 Civic Si. So it's perfectly safe to do it that way.

"45 mm offset is the one that sticks out a little better??"

no-the more offset(larger #) the more inboard it pushes the wheel. The closer to zero offset, the further out(typical rwd fitments are this way).
Good luck.
