Largest tire on stock rims
 

What is the largest tire you can squeeze on stock rims and run with no spacers?

225/45
235 would fit but tire will be pinched and sidewall will be affected. Best to go with manufacturers recommendations. 235 is usually for 8" width.

Some autox guys have have played with 245, but it wasnt very good even for autox.

Like was said 225 is about the biggest you normally would put on there

I've been running 225s...
 

Yeah I've been running 225s since I first replace the tires.

but I also have spacers, so I don't know if that answers your question. I wouldn't want to run anything bigger than that without wider wheels though.

I guess the biggest question though is why do you want the widest tire possible on the stock wheel?

When I have to change the tires I want to max out the improvement in grip without any extra parts/cost.

According profile info you are from Canada. I guess that means you get your share of both rainy days and snow/ice in winter? Too wide tires may also mean reduced grip due them being more suspect to aqua/snow-plane, and also tires will be harder to heat to working temps (and in some cases reduced grip due that). As you asked - "on stock rims", while one can fit even much wider tires then manufacturers recommend, you'll add a lot of extra tire sidewall flex, resulting in mushy washed-out handling/steering. If one of main distinctive traits of these cars is relatively good handling, why f**k it up? Also tire rubber compound will change grip much more then tire width. If it's really grip you are after, get grippier tire model of tires still within reasonable width for specific wheels (stock in this case). That is ideally 205-215 for x7, and still reasonable 195 & 225. One CAN mount even narrower or even wider tires then that. But you've been warned on cons of doing that.

More grip doesnt mean an improvement in driving always. Sidewalls will felx and creat more roll so transitions and feel suffer even if ultimate grip improves.

Is this just a DD or is there a reason you want more grip? Better tires in a proper size with proper alignment will be much better then wide crappier tires

Second car. but I would like to drive it 7 months a year. Cold overnight all year around. Lots of -10c/20f mornings here. ocassionally snow in july. probably have to be all seasons. tired of dressing up to ride my bike, hence the 86

225 will be good.

Michilen Pilot Sport A/S or maybe try the new Bridgestone 980AS if price is a concern

Don't get big tires. Get an alignment.

Michilen Pilot Sport A/S was the best compromise I have seen

There are threads about this.... 245 / 40 is the answer. I did not do it, and i do not suggest it.

Simple, get better tires. To clarify get good summer tires.

Avoid anything Michilen unless they are under $125 a tire otherwise you'll played as a gullible chump, that follows any sells pitch from any fool that wants to sell you an overpriced cheap tire. :slap:

As to the size nothing wrong with a 225 wide tire.
