molony S6

hi guys, i have an s6 1995 station wagon, to which i increased the clearance of about 3 cm. i live in a area with bad roads, bumps and holes and i am facing problems with my tyres, i use 225 - 50 R16, if i shift to 225 60 R16 would it help? anyone has some experience on the issue??? thanks

They have a nice system for telling you which tire size is correct for various wheel sizes .

But to answer your question, 225 60 R16's will be too large in diameter and will affect your speedometer and gearing. If you want higher profile tires I think that you can go with the stock A6 size which was 195/65-15. The only other option I see for 16" wheels is 205/55-16.

So you'll gain that much in ground clearance but your speedometer will read 7.1% slower. At 60 mph on the speedo you'll actually be travelling at 64 mph.

Here's a tire size calculator:

they rub on the rear of the plastic fender liner during very tight (high wheel angle) turns, e.g. parallel parking.

I hit the speed limiter (130 mph) running these tires so do the math for the actual speed.

yes i know it will become larger and it will read slower but you think it will affect something else negatively??? the transmission or fuel consumption for example. my main concern is to gain clearance and less damage to the rims, what do u think???

molony S6

well i am not concerned about acceleration much, but hiting the fender would be a problem, by the way i have lifted my clearance about 3 to 4 cm through suspension, u think it will still hit???

The added air volume of a wider tire will better absorb impacts. Even if the tire is a lower profile number (ie 245/45 vs 225/50) the wider tire will have nearly the same sidewall height and the added volume will help with impacts.

Play around with the tire calculator to find what wider tires are close to the stock size diameter and get tires with the highest load rating you can find.<ul><li><a href="http://www.miata.net/garage/tirecalc.html">Tire size calculator</a></li></ul>

i am not concerned about speed, what i need is clearance less damage to the rims, and i want to keep the 16", this is why i want a higher tyre, but i dont want this to affect anything serious in the car, what do u think??? the 55 instead of 50 will give me 1.12 instead of 2.25cm

Typically, we get rid of the El Rancho look and lower the car 1.5 inches or so. Raising the stock suspension is not in our vocabulary. (At least im my 10 years on this forum)

I chuckle when I read AW with the most abused term Rancho.

My S6 has OEM stock suspension, my winter tires are mounted on this one
My S4 has H&amp;R Bilsteins, my summer tires are mounted on this one.

During warm weather months, smooth roads my S4 will easily out handle the OEM S6. Once it snows, I stuff the S4 in the barn.

During Winter months, where Quattro really shines, my S6 will EASILY out handle my S4 on bumpy, frost heaved, curvy mountain roads.

Call it Rancho, but I will cite personal experience above and assert the manifold joys of having 2, optimized for the season.
