Tire recommendation help
 

I tried searching for my answer but there seems to be different opinions.
I'm trying to figure out the right tires for my 18.8.5 +32 lowered on RCE yellow springs. Just a DD, no track

I know the 3 options are
225/40/18 (I believe this stretches alittle)
235/40/18
245/40/18

Which one would you guys recommend?
Thanks for your time and help!

Get square ones

It really matters on how you like the look of how the tire sits. 235 would be the best imo.

245/35/18 will sit square on the 18x8.5 and be the same OD (outside Diameter) as the stock tires. This keeps the speedo accurate.

Here is a link to a car that has RCE yellows and 18x8.5 +35 (3mm sunk in compared to your wheels) and 235/40/tires. After seeing this I would either get 225/40 or 245/35. Depending on if you want a slight stretch or not.

Thread shows 18x8.5 with 225/40

You will need camber bolts. (you actually can install two sets, top and bottom, to get more camber if you need it) Plus, the bolts are cheap.

All the sizes you listed have a bigger OD.

Stock OD =24.62"
245/35/18=24.75"
225/40/18=25.09"
235/40/18=25.4"

Tire weights: MPSS tires, specs from TireRack
215/45/17=21lbs
245/35/18=23lbs
225/40/18=22lbs
235/40/18=23lbs

Tire calc. It helps!

This is great info! Thanks a lot. Sounds like 245/35/18 is the logical choice. I actually came across that first link of the car on RCE yesterday while trying to find my answer haha.

No problem! Here is a link that shows 18x8.5 +33 (so close) Prokit spring (mild drop like RCE) and 245/35/18 tires POST#25
