My Nissan Sunny JX with 1.3L Carburettor Engine Wobbles on High Speeds. It has 185/65 15r Alloys. Rear Alloys are damaged. I am looking forward to changing the tyres to its actual size. Will it improve the performance? I think the size of this model is 175/70 13r Steel Rims. Also please guide me of the actual Wheel and Tire Size. Will 13 size make ground clearance very low?
Where are you from?

Changing to factory recommended tyre size is better.Wobbling issue could be due to various factors, for example, issues with suspension, steering parts, engine tune up problems leading to excessive vibrations etc
If it's beyond 100-110 it's bad wheel balancing and by wheel balancing if alloys are bad or broken you'll be told by wheel balancing guy.
If the vibrations start coming sometimes below 50 or 20-80 it has problems with axles
It used to wobble alot before I changed the engine. I have also changed steering parts which were causing trouble. Now it wobbles less but still on longer journeys it gives me a headache. I also changed rear suspensions 2 months ago. Now the only thing old is it's tyres.
It vibrates on high speeds but there is something odd on low speeds as well. It feels like car is limping even on slow speeds.
Looks like problem of axle inner or loose cross with broken lock. Get it checked asap.
