Default Nitto 555R 285/35/18 vs 305/35/18

I'm getting ready to put a set of rear tires on my Fikse Profil 5's (18x11). I was leaning towards going with a 295/35/18 street tire. Possibly a Continental DW. But now that I really think about it, I just don't feel that I will get traction with any type of street tire. With that in mind I'm looking at a good middle of the road drag radial (555R). My question is if the 305/35/18 555R runs true to size? I know that the 315/35/17s run extremely small. Was wondering if that is true for the entire 555R line. If they are true to size I may consider a 285/35/18 for fitment purposes since I'm on coil overs and am lowered a solid 2-2.5". Pictures would also be nice if they are mounted on a 18x11 or 18x10.5. Thanks guys.

The 305's you mention are about 1/4" wider than the 315/35/17's. The 285's are about 1" narrower

Thanks for the info 777. I think I can probably fit the 305s without too much problem.

People have been mounting them on oem c5 z06 18x10.5s for years and they fit great, grip great, and have exceptional life considering the traction they yield over non drag radial tires.

My brother (has c5 z06) had f1 eagle gt's in 295/35/18 and the nitto 555r 305/35/18 ran wider and now he has bfg comp t/a 295/35/18 non drag radials which run slightly narrower than the 555r, i'd say they run true to size.

Thanks for the info. I am more worried about the fit with the body rather than the fit with the wheel width though. As I stated before i'm pretty low, so that limits me in some respects to tire width. My 275/40/17 NT05's were actually tucked a little in the rear. I don't mind doing the BFH mod but I don't want to have too much issue with the quarters. I'd rather not roll them all the way if I don't have to. If i can get away with a partial roll or shaving the lip I would be happy with that. Thanks again Vince, very helpful.

I have a pair of brand new 285/35/18 555rII's I might be looking to sell. If you decIde to go that size route let me know. The R2s are the top of the line.

I would def go larger than 285. 285s were stretched onto my 10.5" wheels when I bought them. There was like a half inch of wheel sticking out past the tire. I would go 305 so you don't end up eating a curb with those expensive wheels. I'm also lowered a lot and have no issues with 305 nitto invos

Good info. 285/35 is not a very popular size on LS1tech so I was having trouble finding information on them. I was hoping to maybe stumble across a tire that ran large for its size in 285/35. Looks like 305/35 is the winner. Do you mind sharing what suspension set up you have? How do you like those Invos? I was considering getting those also but in a 295/35. Thanks for the information guys.
