Ok Im currently on 195/60/15 on a 15x6.5" wheel with s-techs. I am wondering if my next tires should be 205/55 or 205/50. I auto-x and really toss the box into corners, I also tend to carry a lot of crap every now and then. So what should I do?

When I did the tire calculator, the 205/55 is .55% too slow and the 205/50 are 2.83% too fast.

People have said that my 195/60's are closer to where the xB's speedo actually is. So would running a 205/50 actually be right around that?

Is there anyone with experience that can help me here.

 

The only thing that I can say is that unless you're really low, a 50 series on a 15" has a bit too much wheel gap for my taste.

 

So you think the 55 is best?

 

how much do you auto-x i've run 205/55/15 before it was alright i'm actually going wider this year though. really it can also depend on the tire you buy.

 

im going to run probably 3 times this year

 

not sure how sticky you want to go then but you might want to consider saving for a dedicated set of wheels and tires.

 

Yeah I was considering get a dedicated track set, but I would still need to know what tire size to get.

 

well a dedicated set depends on what wheel size you go with and offset.

 

I has answer


even more important is the tire your run......

 

I currently run Kumho Ecsta, will probably go with a similar of not the same tire. I wont have a dedicated track set for a long while so I will be using the same 15x6.5 wheels

 

Years ago I used to be cheap and only run take offs from tire shops...

 

I'd go w/50's price will probably be better (slightly) and you won't notice a heck of a lota difference (ride quality & visually) except if compared over the 60's you are running right now! So grab a set of 205/50/15 with a nice performance type of pattern and call it a day! I used to have Kuhmo 711 in that size and they worked fine as a good all around budget tire.
