Bringing this back. Just had another issue with my stock size tires 235/40 R18 and 265/35 18’s. Hit a not so big pothole that caused a small gash in my rear tire. Luckily I was close to home and was able to put on my spare modified Jag X-Type spare. I think I need bigger profile tires. Here are my questions, what bigger profiles can I go with, and why do your (kodpdk) there’s look like they have a bigger profile then mine? Also keep in mind my car is slightly lower due to the installed FD springs.

My new tires do have a higher profile. Now the speedo is correct. I did lower the suspension. I could lower the front a bit more.

How come the profile on your tires look bigger than mine if we are running the same profile?

235/40 R18 fronts and 265/35 R18 rear. So the 10mm wider tires you have equate to a higher profile? Also what brand do you have and had did you get to the size you selected?

I never liked the way the stock tires looked in the wheel wells. I lowered the car to start with, adjusting the stock coil overs. With that I was concerned about the car being to low. I researched the diameter specs of different tires. The front and back are only 1/4 to 1/2 inch taller. I decided on the Komho 245/40 18ZR for the front. Nitto 285/35 18 rear. I worried about the width being to wide on the front and rear. The little wider tires still fit the rims perfect. If you want to race your car, maybe not a good idea.

In short - YES. The first number equates to width of tire, the second is height. However, this height is a percentage basis of the tire width. As 40% of 285 is greater than 40% of 265 the 285 tire is taller.

Additionally, it is not an exact science. A 285/40 from one manufacturer may vary significantly in both width and height from another. The only way to check is to do a comparison on the individual tire manufacturers' website.

I did research the spec on the tires I bought. Width and height. The numbers are a little confusing at times.

Agreed - very confusing. I because very familiar with it during my offroad days in trying to compare metric tire sizing vs US tire sizing, but it took a long time to wrap my head around.
