Best bet, just call them (661)-324-4773. And ask for John.

235/40/18 will fit. Someone posted it before, but I can't remember who.

235/40/18 and the bfg's kdws are a really good tire.

Everytime I see the KDW-2's, I want them more and more. I'm just not sold on these Pirelli's as I was on my BFG G-Force KDW's I had on my Z24!

I have the 235/40/ZR18!! they fit nicely with room for improvenment. I run Goodyear Eagle F1 GS-D3 they were close to $800 installed here locally. I think a 245 35 18 will fit but you will need a wider wheel with a little different offset than factory. I am working on it now I am trying to stuff a 19x8 wheel witrh 245/35/ZR19 on my car but am having problems with bolt patterns. here are some pics of my tires....enjoy!!!
I seen on a post on here that these were rated number 1 on a car and driver tire test. If you want some actual pic on the car let me know and i will take some for you.

p.s. i will second the motion on the KDW's being great tires as well, I have owned these as well. If you dont drive the car in the rain then KD's they are a dry traction only tire, i have these on my Camaro and I love them.

i think the kdw's look like an awesome tire as well

any other guys/girls gonna help a kid out here....i'm sooo stuck i cant decide!!!!!

If the money doesnt matter, then go with the GSD3 235/40/ZR18 if cost is a concern go with the BFG KDW or KD 235/40/ZR 18 The change in tire size had no effect on my speedo

why do you sugjest the goodyear??? i thought the kdw would be a muh better tire

I have a quesion, what is the widest tire you can go but still have a little bit more low porfile?. What size would that be?

the wideist i've seen and the wideist i'd say to go is a 235/40/18...crazt low pro and wider than stock

how much lower of a side wal is that? and what tire do you recomend?

how much lower of a side wal is that? and what tire do you recomend?

well size wize your gaining a half inch of width wich is good and your side wall is going from 3.8in stock to 3.7 with this...so a lil lower but much wider

as far as tires go i'm stuck between the BFG KDW-NT or the FALKIN RT-615

is their any way we can fit a 235 35 18? that would be a even lower profile right?

yes it would fit and yes it would be a lower profile but at that point your tire size is so outta wack from the stock size that your spedo wont read rite

yeah true.
