piston Posted March 28, 2007 Share Posted March 28, 2007 i was wondering im running 16x7 but measures 8 inch from lip to lip but thats considered a 7inch is what they say. i want to run the widest tire possible and was wondering whats the widest i can go on it? i was told 245 was the widest. i have clearances either side. searched but mostly came up with clearance threads. 245-45-16 is what i might run. thanks.

blueovalz Posted March 28, 2007 Share Posted March 28, 2007 im running 16x7 but measures 8 inch from lip to lip but thats considered a 7inch is what they say Advertised widths are between the rim lips. Usually the outside-to-outside dimension of the lips is 1" more (each lip being about 1/2" wide) In general, a 245/45ZR16 is designed to fit a wheel that is 7.5" to 9" wide (advertised width). Depending upon the tire manufacturer, this could go up in a range from 8" to 9.5". Based upon this I would reconsider this size of tire on a 7" rim.

JMortensen Posted March 28, 2007 Share Posted March 28, 2007 205 fits right on a 7" rim. It's not the biggest tire you can fit on the rim, but it's the one that fits right. Quote Link to comment Share on other sites More sharing options...
vashonz Posted March 28, 2007 Share Posted March 28, 2007 I'm running 245-45-16 on a 16x8.5" wheel, and it looks really good, much narrower and it would probably "bulge" out too much. And its not "stretched" at all. Quote Link to comment Share on other sites More sharing options...
Bartman Posted March 28, 2007 Share Posted March 28, 2007 There has been quite a bit of discussion regarding tire widths for rims with 7" advertised width. I'm run 225/45-17 on my 17x7 rims and I believe they are the widest recommended tire for a 7" wide rim. Although that's the widest recommended tire there's been some testing that suggests you can actually get better traction going with a narrower tire such as 215. These threads discuss 17" rims, but I think the data would be similar for 16" rims. http://forums.hybridz.org/showthread.php?t=112952 - expecially post #2 http://forums.hybridz.org/showthread.php?t=113577 Quote Link to comment Share on other sites More sharing options...
Sr-FairladyZ Posted March 28, 2007 Share Posted March 28, 2007 Yes, 245 is pushing it on 7''. Your sidewalls are going to be like muffin tops. Not the nicest approach visually. Aspech when the in thing is stretching smaller width tires on garbage can width wheels. Quote Link to comment Share on other sites More sharing options...

wheelman Posted March 28, 2007 Share Posted March 28, 2007 I'm running 225/50-16 Falken RT-615 Azenis on 7" wide rims. The guys at the tire shop had a fun time getting them on so I would say 245s would be pushing it especially in a 45 profile. Which tires are you thinking of running? Some manufactures will push the size specs so one tire may be wider and/or taller than another of the "same" size, consequently if you want to maximize your tire size you should check with a shop that sells the tire you're interested in.

piston Posted March 28, 2007 Author Share Posted March 28, 2007 i was thinking about running some nitto or or toyo or khumo. depends on the prices. 225 is what i had plan for in the first place. 225 is what ill probably be running. fat tires looks nice, but dont want to push it. maybe if i roll up on some 235s. wheelman, got any rear pics?

Garrett76Zt Posted March 28, 2007 Share Posted March 28, 2007 I know its a drag tire but I run 235 drag radials on a stock zx turbo wheel. I think its like 6.5" wide, haha. Quote Link to comment Share on other sites More sharing options...
wheelman Posted March 29, 2007 Share Posted March 29, 2007 I can take some rear pictures. I had to roll my rear wheel wells and trim a small amount from the wheel well part of my air dam in front to prevent rubbing. Have you done much actual looking for sizes larger than 225 in a 16" rim? I wanted to run 40 or 45 series tires in 225 width but had a very hard time finding any tires in that size. I considered going to 245 but now that I've got the 225s I'm glad I didn't try, they woould have been too wide and a real pain to mount. Edit: I am running 1.5" adapter/spacers with the rims I have. This may be part of the reason I had a rubbing problem. Before I converted to coilovers I had about 1/4" clearance between the tire and spring so couldn't really use a smaller spacer.

Matt K Posted March 29, 2007 Share Posted March 29, 2007 I've run 245-50-16 on 16x7" wheels without issues. There is a bit of tire roll, 225's fit better & were more square/flush on the wheel. Quote Link to comment Share on other sites More sharing options...
piston Posted March 29, 2007 Author Share Posted March 29, 2007 tires size is not an issue to find for me. whats gonna be safe and work is what im looking for. i would love to have 245s but i might get 235s. 235s to me, are the hardest tires to get. fender roll and clearance is not an issue. ill be running zg flare. right now i have 205-55-16 and man they look ugly. heres a pic in my album if anyones interested.

JMortensen Posted March 29, 2007 Share Posted March 29, 2007 If you're running flares why not take advantage of that fact and run a wider rim with the correct size tire on it? 16 x 9 with a 255 or so should fit if the offset is right...

240hoke Posted March 29, 2007 Share Posted March 29, 2007 All tire manufacturers post the recomended wheel width range for each specific tire and size on their website... I think that would be the best place to look. Quote Link to comment Share on other sites More sharing options...

I agree, The skinniest your rears should be with ZG flares is 8.5 with a moderatly - offset like -19 to -30. I have 8.5's -30mm offset in the rear with 225/50's and they fit really nice. Dont make the mistake of running ZG flares with 7'' rims and spacers and all that jazz, I've been there and your never satisfied, thats if you dont loose a rim on the expressway first.

Scottie-GNZ Posted March 29, 2007 Share Posted March 29, 2007 General rule of thumb is that the wheel width should be no less than 70% of the tire tread width. Quote Link to comment Share on other sites More sharing options...

I think that would be the best place to look. Yup... what 240hoke said ^^^ above ^^^ !!! The 245 is the widest part of the tire (the bulge). BF Goodrich has advertised that their 245/50/16 can fit on 7.0 - 9.0 inch wide rims. This may not apply with other tire manufacturers.

Guest 280ZForce Posted March 30, 2007 Share Posted March 30, 2007 I run a 225 wide tire on my 16x7 Riken mesh wheels... this is pretty much the widest tire you should run on a 7" wide rim for safety reasons imo. Quote Link to comment Share on other sites More sharing options...
