I'm aware the 1970 Challenger T/A was the first production vehicle to offer staggered size tires: E60 x 15-inch in front and G60 x 15-inch in back.

One of the reasons I stuck with 17" wheels was so I could get RWL staggered tires that are bigger/beefier in the back. I now realize RWL tires aren't available, but I still want staggered tires.

I inquired with Matt from Discount Tire in the sponsor section. His suggestion is to run 215/65-17's in the front & 225/65-17's in the back. His information is very helpful & I would also like the advice/opinion of Challenger owners.

If I keep stock size 215/65-17's in the front, what size will best give the back tires a noticeable bigger/beefier appearance without overdoing it?

Thanks! :thumbsup:

I would recommend a 245/60R17 tire on the rear. It will give your car a more aggressive look and will be close to the diameter of your front tire (i.e., will not throw your speedo off).

The 215/65R17 has a 28.0 " diameter; 742.8 revs. per mile

The wider 245/60R17 has a similar 28.57" diameter; 728 revs. per mile.

I truly appreciate your advice.
Do you suggest keeping the same size in front or going with something slightly larger like a 225/65R17 tire?

I would go 2cm wider at a bare minimum if I wanted it to have any visual effect. On my Indy Ram I run stock 275/60R17's front and 305/60R17's rear and it's a little hard to notice any difference in width.

The closest thing to your stock 215's would be a 235/60R17, only 2 revs/mile (fewer) difference...but the 245's would look better IMO.

It's not just width. I'm hoping to be able to get a wider/taller tire appearance in the back like on the old school muscle cars.

What do you suggest?

Also, is the speedometer calibrated on the front or rear tires?
I can't imagine it would cost too much to have it re-calibrated if necessary, right?

I've never heard of a car's speedo being driven off anything but the drive wheels.

If you're looking for a taller AND wider tire you'll have to go at least 245 with a 60 series or larger aspect raito. I have no idea what will fit on an SE but you might want to look around at what other SE's are running for the retro look.:scratchhead:

If you make a tire taller and keep the width the same it will look skinnier. Case in point the tires on an Indy Ram and a Rumble Bee are both GoodYears, both 275/60's but the 3" difference in diameter make the 20's look a good inch or so skinnier.

The 215/65R17 will give you the most dramatic difference in width between the front and rear wheels if you use the 245/60/17 on the rear, if that's the look you want. However, I would go with the 225/65/R17 tire on the front. Its diameter and revs per mile are almost identical to the 245/60/17 (28.51 vs. 28.57; 729.5 revs vs. 728 revs) and will still give you better handling.

For the purpose of practicality, I've decided to keep the same tire size all around, but I would still like the old school "more aggressive" big tire look. I found that Diamond Back Tires has 235/60R17 redline tires.

Will putting these on 17x7 wheels instead of the stock P215/65R17 accomplish this look?
Will there be enough steering clearance in the front?

I greatly appreciate your continued assistance!
