    Nitto Tires

    Ok im trying to decide on tires for my 17x 9 Cobra R's.I am looking at the Nitto 555 -- 285/40/17 rear and 255/45/17 front since they both are 25.94" tall.Anybody run this combination?Any input appreciated.

    Those sizes are a nice staggered combo for 17" wheels on an MN-12. Pretty sure that is what David Dalke has on Connie's black XR-7.

    I ran 255/50 on all four corners with my 17's. The Nitto tire is pretty wide in a 255.

    Exactly what I had before going 18's. Will buldge a little in the rear on a 9" but not much

    Well maybe i will go with 275 on the rear.Did you have 255 on the front?If so did you have any driving problems like bumpsteer?I read some where the Nittos were narrower than other brands thats why i was going to go with the 285.Also did you change any alignment setting with those tires?Would it be best to get mine aligned before or after i put the wider wheels/tires on?I just did a total rebuild of the front suspension also.

    I think you meant tramlining and not bumpsteer. The Nitto NT555 did very little tramlining on my SC with 245 on front and 275 on the rear. Now that I think about it it didn't have any either when it had 255 NT555 all around.

    Most people go with 245-45-17 Front and 275-40-17 rear with the 17" x 9" wheels. Both tires will have the same diameter and it's very close to stock, so the speedometer readings and fender gap will remain the same. That's what size tires I had on my 93 SC when I had 17" x 9" Cobra Rs at stock ride height. BTW, these are Nitto tires too.

    David this is what it looks like with the wheels and worn out 255 tires.I also put the Eibach springs on the front and i am going to have to cut them or cut the ST springs and put them back on.It has ST springs on the rear.The front is way too high!!

    Looks good, just needs to come down an inch or so in the front. I used to have 255s on all four wheels too, but I think the staggered setup looks a little more aggressive.

    My car drove great no bump steer at all. I think rim offset will affect that more. Do the 285/255 Perfect staggered look. 275 will be short.

    I was very happy with the Nittos. Now have sumitomos...not so happy

    Id also align with new tire setup and keep factory alignment. Every time I go more aggressive I get more aggressive tire wear!

    Damon is correct about the 285 255 combo being a slightly larger diameter. The 275-40 and 245-45 are not stock diameter as I indicated earlier, they are 25.7" diameter and the ones Damon is suggesting will be 26.0" diameter. When I mentioned being close to stock diameter I was thinking if the 18" 275-40 and 245-45, which are 26.7".

    That said, I'd still go with a 275-40-17 and 245-45-17 because there will be a much bigger selection than you will find in a 285-40-17.

    Yeah your Teal car sets good!!I ordered the 285/255 combo today. Did you have to cut your front ST springs to get it down that far? Mine has the ST on the rear and it sits just right.I dont know why it sits that high in the front with a 1.5" drop.Maybe its the 70 lbs or so of weight gone up there.Im going to put the ST springs back on the front and see what it looks like before i have them powder coated. Do you think it would be ok to cut the ST springs if needed?
