Tyre size comparisons

[steveinjapan]

My car has 145/70-13 and 155/65-14 Michelins on stock "telephone dial" wheels. I recently discovered a certain lack of emergency stopping power and would like to increase sizes a bit. How would 165/60-13 and 175/60-14 work out? The rear would be about 1/2" taller and the front about the same as now, just more rubber on the road all round.

Or can I go any wider with the stock wheels?

Thanks,

Steve

Here on cobble trails, we like a tall tire. I installed 175/70R14 on rears and have had some rubbing issues under spirited driving. A roll of the wheel pinch weld would easily do. 170/s probably wouldn't scrub. just haven't got around to rolling mine yet. I've got the Sparco rims but believe they are the same offset etc. as your "dials.

Its not added tyre size you need, just some weight over the front wheels

Just put some bags of sand in the front in place of the spare wheel

Or maybe find a passenger who isn't afraid of driving with me.

Seriously, could I go as wide as 175/60 or 185/60 on the rears? A tad extra height would be good too.

we had 175/60 potenzas on the back of ours for a bit. it drove fine without any issues on a 6" rim but i didnt like the way it looked at all - they looked quite ballonish compared to the fronts (165/55) on a 5.5" rim.
after a lot of looking around at what the japanese guys were running i switched to 185/55 on the back and 165/55 on the front and its perfect (advan A048's).
ive had no probs at all until i had to roll the rear arches for lower offset wheels and that was only really because the car is lowered a lot.

Thanks.... what are the stock rim widths though? I like the dials and don't want to change them.

I'm looking at putting 185/55R14 on the stock rear 5" rims. Car Bible says it is OK, but some tire shop ads specify 6" rims for that tyre.

I would prefer 175/55R14 but apparently they are no longer manufactured.

Anyone used 185's on stock 14" rims?
