No, a Delta 88 is not a gbody but you might have more room to fit a wider rim than the gbodies.
If you are trying to fit the widest rim possible without sticking out of the whellwell you will have to do some mock ups. There are a couple of relatively inexpensive tools for this out there for doing tire and rim fitment.
I still think 10" on the front is going to be too wide even for your large car.On the rear it is possible it will fit.
You could also just buy a pair of the rims you think will fit and carefully slid them on the lugs just to get an idea of where they will sit in relationship to the whellwell. Without the proper tool it is really just trial and error and some educated guessing.
If you can find a local tire and rim store that will be patient enough to work with you they might let you try some different rims with different backspacings as long as they know they are going to end up selling you something.
 
Ok, yeah i understand what you mean now.. i think i would buy just 2 rims in 10x15" first.. and then try them on my car rear and then in front.. and with tires on too..

i took a pic of my car today.. the wheel standing back now is just 235/60/14 tire on 7" wide rim. i dont remember the offset right now.

i edit the pic with a yellow market that i will maybe see if the rim would be in 10" wide.. well i dont know yet but maybe..

anyway i have a fenderroller too if i must use it..if the tires will be a little to wide.. hmm well...i have now sent a question about offset about the rims to the storedealer if they have some ideas about offset to my car.. if so i would buy just 2 rims first and try it on rear and front🙂
Btw, i think maybe i friend of me have a set with 10x15 steel rims with 295 tires..i will give him a call and try his wheels on my olds, maybe i can get some answers then 🙂

thanks for answer anyway 😉

If you have someones rims you can borrow even better, even if they are not 10" wide or the wrong backspacing you can get an idea what will fit from there.
Also on another note most people when mentioning rim size state the diameter first then the width such as 15 x 10 for your rim size. It might be different where you live but this is a pretty much a universal rule.
 
ok i see. yes my friend have those wheels so i will test it soon, i will come with pictures too.
 
Take your rear wheel off. Put a straight edge on the brake drum where the wheel mounts and measure from that back to your frame.

On the fender lip, hang a string with a few washers tied to it as a make shift plumb bob. Measure from the straight edge back to the string.

Add those two numbers and you now have the total clear width between the fender lip and frame. Subtract a 1/2" from each measurement to be on the safe side. If you have anything else that sticks out further than the frame, ie shocks, etc. then you'll need to measure to those and determine if they will be a problem.

Measuring for rims is not rocket science. 😉

And just an FYI, when talking about rim sizes the diameter typically goes first and then the width. I keep reading your post thinking your putting a 10" diameter x 15" wide wheel on this thing. :lol:
 
I agree that taking an overall measurement is a good place to start but still doesn't account for the tire section width(which can be 2"+ wider than the rim it is on) and tire height and the frame and wheelwell clearance needed without rubbing and finding the rim you want with the right amount of backspacing isn't always that simple.

Also I looked at Summits site and found the 255/60R15 is recommended a max of 9" rim and they don't even list a 265/50R15 on their site but they do make them but it is a very uncommon tire size so I couldn't find any rim width recommendations.
Another thing I have found is different manufacturers for the same size tires mounted on the same rim width are not always the same specs as they list. Like I said there is more trial and error than one measurement.
 
Every tire manufacturer lists the section width of the tire based on a certain rim width size.

Anything wider than the stated rim size you have to add .2" for every half inch increase/decrease in wheel width.

Your 255/60R15 tire in a BFGoodrich has a 10.2" section width on a 7.5" wheel. ASSUMING you could even get it to fit a 10" rim, the section width would increase by a full 1" because of the wheel width. So you'd need to measure for something with 11.2" section width.

Just so you know, even a 275 tire isn't recommended to fit a 10" wide wheel. However it's only a 1/2" difference which isn't as big of a deal. I have 245/45R17 tires on a 9.5" rim even though they were only recommended with a 9" max rim. The tire guys I had install them were cursing a bit trying to get them to stretch properly during install but they fit and seal just fine.
 
yo, long time no seen... :lol:

now i have some steelrims and its about 9,5" wide.. this have stand on a chevy camaro so this rims fits perfekt on the brakedisk,,,so now i know the bolt dim are 5x5 / 5x120.. (i think).. vell anyway its 295/50/15" tires on them.. and the BS is about 5,6" i have found out... the rims (10x15" i actually going to buy have 4" bs..so this is a good start i think... but i have just test only 1 wheel on the car right now.. and the car is not on the ground still yet... but very soon.. then i will find out more about clearance and if something will hit the rubber.... with 5,6" bs and 295 is very close to hit the frontparts maybe.. but i will find out more soon... anyway some pic..

5,6" backspace on 9,5" rim looks like this.

i will try this wheels rear too... i think anyway in my mind that 10x15" with 4" BS will fit perfekt...and then find out what tires i will use later.. this 295 is soon empty..so i will have them over on the new 2 rims i will buy first and then test in front and back...and find out if i must have some thinner tires than 295 or not 8)
 
Hello, a little update on this tread,.. iv got my new rims..but i must use 8" rim in front...so i buy 8x15" rims and 225/60/15 tires.... and will buy new 295 tires back.. some test pic :lol:
