yes the annoying tire question , but this is my first post , hello everyone , ok back to the subject...... I am new to street tire size, always had mud tires for trucks , I want to go with an 18x10 wheel, with a wide tire that will fit without any fitment issues , or you tell me if a 17x10.5 is my better bet for more tire sizes. Ive seen one guy on here with 315x35x17 but I want something like that for an 18 wheel, price is a factor. thoughts and any help much appreciated .

I have no intelligent input on the tire topic........... did you buy this car out of Statesboro by chance?

If you want something with a pretty wide tire for an 18 and price is a factor, well then you may really want to look into 17x10.5 then because there is a cheaper and wider array for a 17 wheel rather than 18 as well as cheaper price. But you can't beat the look of a beefy 18 wheels out back! IMO!

I have 315/35/18 out back and they costed 550 shipped but man were they worth it!

I asked about your tires the other day , thanks though , im thinking the same thing about the 17s alot more to choose from .I still want the low pro look nothing track .

17 inch tires are going to be cheaper then 18 inch by a pretty good amount. You can run 315 tires on a 18x10 wheel but they are going to bulge a bit. I'm running 18x10 out back and run 285's at the moment. When I need new tires I'll probably try to find a 305 series. To answer your question about fitment issues, 17x10.5 with 315's won't have any rubbing issues. Anything bigger then that you'll have to do some modifications to run them.

I did some work on it.

Is it number 15xx or x801? Something like that. I had my hands on two of them at the same time, not sure which one you wound up with.

18" tires are more expensive than 17" tires. People who run 18" wheels usually reduce the tire sidewall so that the overall diameter stays the same. This keeps your speedometer accurate. Stock size tires have a wall height of 110 mm (245 x .45 = 110). A 275/40-17 and a 315/35-17 have the same tire wall height. That's why those tire sizes are so popular. These tires have an overall diameter of 25.68". The closest wide 18" tire is a 285/35-18. It has an overall diameter of 25.85". You can run those on 9.5-11" wide wheels. For the front you might want a 235/40-18. They fit an 8-9" wheel. They have a 25.40" diameter. There are several manufacturers that make tires in those sizes.

Another combination that could be used is a 275/35-18 on the front (25.57" diameter) and a 315/30-18 (25.44" diameter) but according to 1010 tires the 315 need to be run on 11-12" wide wheels and only a few manufacturers make them.

Edit: Fixed tire width.

yes 833 , any history I should know about? , pm me please since its off topic. any info will help me out though .

[bulloch27]

No real history to speak of. It was ugly, he made it pretty. He dropped a lot of money making that car look as nice as it ran and then sold it the day after I finished with it. You got a nice car.

I dont have much experience with condition of cars , actually this is my first car I have owned , I can tell its had a paint job and passenger side was slammed into a curb , hint (thats why Im looking at wheels ) , heater core replaced , and trans worked on at somepoint , deff not a show car , Im keeping it on the street though .

[02NightRider]

A 305 doesn't have to be run on an 11" yet alone a 12" inch. Hell the recommended tire size for a 10.5 is 315. And just because you can run a 285 on a 9-11" wheel doesn't mean you should.

perfect just what im looking for , the 285/35 18 is looking good , hope to make it even with the fender of course , going with black and chrome lip cobra r wheels

The car was stipped to bare metal, minor dents repaired, primed and painted (everything removed except for back glass, I mean everything). Expensive paint job. I didn't see any curb/accident damage. The heater core was bypassed so I replaced it with a new core and reconnected it. 3-4 synchro was shot (as are many T3650 trannys) so the synchro, shift fork and rod were replaced. You got a very nice car, but I agree it's not a show car. All the original Bullitt parts are there and all the pain in the ass hard work was done when he sold it. Literally I finished the car two days before he sold it.

so width wheel size are you saying needs to go with a 285 ? safe factor

I have zero complaints on the work done , I'd take it you did most of it , 3rd gear grinds from time to time , and just one thing I cannot figure out is this constant woomp woomp woomp , while crusing in 4th and 5th, does not speed up or slow down its just there period , vibrates the car . this infomation really helps me out knowing what was done.

Cause 5th is overdrive that's your mpg gear while on the highway... get to speed on highway slip in 5th get 26mpg

That was a typo. I meant 315/30-18s. I'll go back and fix that. The tire size calculator said "No tires found in this size." when I used 305 so 1010Tires.com doesn't carry them.


We are also talking about 18" wheels not 17" wheels and we are talking about a much shorter sidewall. That makes a difference in how much you can go out or come in. Yes a 315/35-17 is recommended for wheels 10.5-12.5". But note, 10.5" is the minimum. I've been running them for years on a 10.5" wheel. The shorter sidewalled 315/30-18 is recommended for wheels 11-12". You can run them on a 10" wheel. A lot of people do but it isn't recommended by the distributor and it will probably cause the centers to wear out of the tires unless you drastically drop the tire pressure. To get even tread wear on 10.5" wheels with my 315/35-17s I can only run 20 psi. You don't have to believe me. Go there and check for yourself.

I run 285 on my 18x10.

I understand what your talking about now eagle. I thought you were talking about width, not sidewall.
