275 front tires on ACR

[Norwegian]

Like the tonic says.
Will it work on the stock rims?
I only drive on the street, and I think the narrower (like a regular viper) will be better on the bad roads we have here.

Anyone done it?

Is the OEM ACR front wheel a 10" or 10.5" wheel?

I don't think it would matter either way, as most 275 tires I've looked at are designed to fit on rims anywhere from 9"-11" wide.

Will it look a bit more stretched than a 295 section width tire? Sure, but I'm sure you'll get used to it.

I have ran both and can't feel any difference.

You did not say YEAR of ACR ?

Stock ACR Wheels?

You did not say sidewall series, 40-35-30 ?

Only accurate answer with half info is "MAYBE" or "Probably"

Yes stock 2009 ACR rims. Stock tire size on a regular SRT10 is 275/35-18

[SA Heat]

Here's a general size comparison between 275/35-18 (left) and 295/30-18 (right)....

Overall diameter: 25.6" 25" -0.6" (-2.4%) The difference does not exceed 3%.
Section width: 10.8" 11.6" +0.8" (+7.3%)
Circumference: 80.4" 78.4" -1.9" (-2.4%)
Sidewall height: 3.8" 3.5" -0.3" (-8.1%)
Revs per mile: 788.5 807.7 +19.3 (+2.4%)
Clearance: Clearance changes to 0.3"

probably gonna help to have thicker sidewall, but not by much. I run 295-35-18 (4.06'') and the stiffer structure of the tire makes it probably as harsh or worst than 275's.

Maybe you should focus on the suspension instead. If you still have the stock suspension:

Front: 514 lb/in
Rear: 1085 lb/in

That's sure pretty intense on bad roads....


For reference, gen 4 SRT-10 is:

Front: 210 lb/in
Rear: 525 lb/in
