Advice on wheel/tire package (yet another thread!)


Recommended Posts

I know there are a lot of threads related to this issue, but I guess everyone has a bit of different needs. That said here is what I would "ideally" like, which I can't find . So I am seeking advice on what other options should I look into. Then, once I find something the fun part of proper backspacing starts.

Ideally I would like to keep tire diameter in the ~26s, run 245s on front and 295s on rear. I have been looking at 17" Magnum-like-styled wheels. The front is not much of an issue but I am not finding much for the rear. A 295 or even a 305 puts me on the 17x11 wheel size range, which I can't find standard. I can see them custom but the price is through the roof. Maybe I should consider 18" and/or settled with 275s. I like the Magnum styled wheels but I could be open to other ideas, but it makes me a bit nervous spending all this money and then not liking how they look on the car.

I am all ears and if you have a similar setup please post pictures.

There's not a lot of choices in the 295/17 tires with a 26" diameter. The recommended rim width range for most of them is 9.5" to 11", so a 10 inch rim width should be good.

An alternative would be 285/40/17, 26" diameter, less than a half inch narrower, can be installed on 10" width rims, and more available.

I could get the 26.1" 295/35/18. However, I don't know if I like the idea of wheels of different diameters.

The more important issue is that I am not finding alloy Magnums sizes 17x10 or 18x10. It seems that they stop at 17x9.

I have these, not a true Magnum but a modern take on them. 245/45/18, 18x8 front, 285/40/18, 18x9 rear, 5.25 back spacing on rear. Rear tires are 27” tall. No tire clearance issues. Ryan

Which wheels are those?

Wheels are US Mags Bandits, not that expensive either. Ryan

I like those but I would like them in 17x10. There are a very few options in 17x10 or even 17x9.5.

This is the only thing I can find that is close in design, 17x9.5 and at decent price. I can get custom made but it ends up being $500+ a pop.

So the backspacing on these is 5.05" which may be too little and the tire may stick out too much :(

With a 9.5" wheel I think I need a 5.5" backspacing or +6 mm offset.

These are 285/40-18's on 9.5 for the rear and 245/45-18 on 8's front. Still sits high but she's not fully together yet.wheels2.thumb.jpg.a3077673bfe032c261359bc665819d40.jpgWheels1.thumb.jpg.049f680f5c7e01722e7e3b555398f444.jpgwheels4.thumb.jpg.e72f0cd84519b7b80a378aa0dc02be8c.jpgWheels5.thumb.jpg.82b7722064aeb69f120fc5b8ebfb7444.jpg

I saw your earlier post and I really like those wheels. Where did you buy them? I can't seem to find them online. Do you know the backspacing? I hope they have them on 17s, but since they have many spokes, the 18s may not look that bad.

I believe the BS is 5.25. Here is a link and they do have them for 17's. I was trying to get as close to 28" tall as possible without going super wide or too much side wall. I kind of like the bigger wheel lower profile tire on these big cars. Although the traditional 295's on the 15's are classics.

The problem I face with all these wheels that I like is that the 17s stop at 8 or 9. I can see many of their wheels in their site but they don't sell direct. Where did you get yours?

I just saw these FR500. They look cool. They are 17x10.5 and 17x9.0. Thoughts?

I don't think the backspacing will work on those. You might want to do a mock up and see.

I'm with you here. I would do a mock up. Not sure about the offset. I have a tool like this.

According to my calculations based off my current setup the rear will fit well with 315s. I still need to double check the width of my current wheels. For the front I would need a 1" spacer (bolt-on) for either 245s or 255s.

I am definitely not going to rely solely on my theoretical calculation. I have to do a mock up. I like that tool you suggested.

I found this thread where he used FR500 wheels as well. It doesn't seem that this member is still active.

Assuming I can figure out the backspacing, which one you think would look better. I like the black/chrome look but my car has silver accents which may match the Silver or Anthracite finish, but it may be too boring. Thoughts?

Black/Chrome:
