What size are your font rims? I have 245's on 9" rims and they tyres don't look stretched.

Check your rim size. should be on the wheel next to valve.

Assuming your on 9" rims;

MinTyre width 235
Ideal Tyre width 245/255
Max Tyre width 265

If you're on 8" rims;

MinTyre width 215
Ideal Tyre width 225/235
Max Tyre width 245.
