Currently I have 245, how big can you go?

 

That depends on the tire profile among other things, but in a close to stock profile... 255

They aren't as common, so your selection will be limited. You're better off just finding a 245 that gets better traction. Unless you're doing it for looks, in which case, I don't think I could tell the 1cm difference from 30 feet away...

 

As you go wider the tread gets less flat. If you're after the best performance, stick with the recommended tire size.

 

As noted above, not a lot of choices, but how wide you can go depends on:

-type of tire you need (street, road race, drag, all-purpose, etc.)

-diameter of tire you need (limit to stock diameter, or go larger for drag tires)

BFG, for example makes 16" tires in their Radial T/A line (all season radial) up to 295 section width that will mount on an 8" wide wheel. But they are in diameters ranging from 26.5" - 30.1" (versus a stock diameter of 25.7" or 26.1").

265/60-16 - 26.5"
275/65-16 - 30.1"
285/60-16 - 29.5"
295/50-16 - 27.6"

I'll move this to the Wheels and Tires forum.

 

Im running 265/45-16's on my stock salad shooters.

 

I assume you looking for the widest tire that will still allow the car to handle safely. Going much bigger will just distort the tire and the contact on the road.

 

I'm asking because I saw a guy who has a WS6 Formula LT1 and it has some big *** tires on it, they werent drag radials I dont think. They looked to be around 285 or so. Is that possible on a WS6 wheel?

 

If I'm not mistaken, the WS6 wheels weren't 16x8...

 

Yep, AFAIK they were 17x9, and came with 275/40 tires.

285 is about as big as you can go on a 17x9 before you start running into the same distortion issues as going bigger than 255 on a 16x8, unless you start increasing tire diameter.

 

What brand? I've seen the Kumho V700 and V710 road race tires, but nothing in a street tire.

 

Kumho Ecsta V700. Not a street tire, but streetable. My car's not a daily driver though.

 

The widest tire wheel combo i have found is 17x11 with 315's and they need a little modification to fit. The 285's on the 17x9.5 is another size i see a lot.

 

Both my brother and i run 245 on front and 255 Falken Ziex ZE 512's on back.
