Tire recommendations ?

235-50-18 or 255-45-18 for front
245-55-18, 255-55-18, 295-45-18 for rears

Pick what you find

Sorry to dust off this old thread, but after searching for an hour this is the info I need. I have the OEM size 235-50–18 Nittos on the front, and bald Nitto 265-50-18’s on the back (4.32% ratio).

—> So, I can get Nitto 255-55-18’s for the back, but that’s going to take the front to back ratio up to 6.5%. Is that going to confuse the traction control?

295-45-18 rear is tempting, and almost exactly the same ratio front to back as my 265-50-18’s (1.2” difference instead of 1.18”), but a bit too wide for me I think, and I believe some people have reported a few issues with them.

Thanks as always for your feedback.

P.S. I’d like to go with the 3/4” wider 255-45-18’s next time on the front, but with 255-55 rears I’d have a 7.3% difference front to back, which would probably give TC issues.

People have run the 255-55 without issue with stock front size, if you plan on the 255-45 front at some point, I might not recommend 255-55. Plenty here have 295-45 rears on stock rims, just make sure you choose a sidewall rating same as stock.

Outstanding, thanks for the info. These will be 6/10ths of an inch taller than the 265-50’s if I recall correctly, and 4/10ths narrower, but also 4/10’s taller and wider than OEM.

WRT the size differential and traction control I’ve never seen anything from Ford on that, just s 3-6% range mentioned here, so that 6.5% front to back should be OK.

I've never run the 255-55 rear size. Other members have when choice was even more limited than today. Every car is different and tolerances in mfg may or may not effect it. There is no guarantee it won't effect it.

Thanks, appreciate the info. Shame the 265-50’s are no longer made, as that was the perfect solution. In looking at a tire size calculator these 255’s are .39” wider and .42” taller than OEM, and have a 1.32” larger circumference, so when the speedo shows you doing 65 you’re really doing 66.

To be sure I might just default back to the OEM tires, but could get these now for a good price. I’ll check it out, thanks again.

BTW, looking at their specs, 295-45 might be the perfect solution as they’re so close to OEM in everything but width. (I’m seeing a 4.4% front to back difference to OEM fronts, 1.2” taller vs. 1.36”) I was only thinking there might be fitment issues as they’re 2” wider than OEM and 1.2” wider than my 265-50’s. I would get Nittos if available so the sidewall rating shouldn’t be a problem.

WRT the 255-45 fronts, are there any rubbing issues with those while turning? I’m seeing they’re .22” lower but .80” wider. With the 295 rears those would look good in front next time around.

I have the KDS, Nitto Motivo's, Nitto G2, and General on for panthers.

The G2 are hard and loud... Unreasonably so, compared to all others and not befitting our big sedans. Not a fan at all. Have been contemplating changing out tires, and putting the G2 on a car I don't drive often.
 
255-45-18 front, no issues turning, rubbing..my car is lowered and they still don't interfere.

Thanks, good to know. I went with the OEM size last time which are wearing well (with Carfixer’s alignment specs), but think I’ll go with this size next time.

I have the 235-50 stock Nitto 555’s on the front, but don’t know if they make anything but G2’s now. I’m a fan of Nittos in general, and will see if the 295’s I’m considering are G2’s or not.

i have the 285s on a few marauders with stock width wheels, everyone on this site says they cause the car to sway and not ride right.

Cars ride and drive fine, i take corners fairly quick and never have i had the rear end shift around like some here bizch about.

i would load a picture, but this site isnt loading pictures anymore

Yea, I'd love a pic too! My old 285s are still good for burnout competition at my local track, but they were replaced on my widened rims by Nitto NT05Rs. I'd love to mount them on stock rims (I have a spare pair) if they would stay on factory rims!

Trouble is that although you are 1.6” wider than OEM with that rear size, you are 6/10” taller, so if you have stock fronts your front to back ratio is 7.2%.

If you have the .80” wider 255-45-18’s fronts mentioned here and go to 285-50’s rear, then you jump nearly a full percentage point to 8.1% front to back difference, which is a factor if you have traction control.

I love the look of these though, but with TC and planning on going with those lower wider fronts next time, for now I’ll have to stay close to OEM height for the rears.

Nitto states they are for 9-11.5" wide wheels. Ours are 8" wide.

They fit in the same way the stance kids fit 225 width tires on a 10" wide wheel. It "fits".

Discount tire seems to claim they have 265/50/18's in stock (option is not greyed out like other sizes)

https://www.discounttiredirect.com/buy-tires/nitto-nt555-extreme

I checked, hoping to get lucky, but although they list them their plan is to order them direct from Nitto on behalf of the customer. The rep even called Nitto for me to confirm they are out of stock. Bottom line, Nitto just didn’t sell enough of them to keep the size.

Yea, I did all the math before going 255 front and 305 rear (on widened rims) last week. I just wanted to know if I could sucessfully use my 285 with an extra set of stock rims I have for a burnout competition. :-)

Cool! Well you’ve got the tires for it now. That’s a lot of rubber under the car.
