Hi all, I just sent my Vios to the service center yesterday and found out that my front right tyre has a small bulge at the side (probably hit a divider or smtg). I'm thinking of replacing it but not sure which are the better options:

1) Replace the bulged tyre with the spare tyre (they're the same size if i didnt check wrongly) and continue using the car. The bulged tyre kept as spare.
- since I don't drive my car much (2 years+ in, about 12k mileage), was thinking if i can do this?

2) Replace the bulged tyre with the spare tyre, go change the bulged tyre and keep as spare.
- with this then i can utilize the spare tyre all all 4 of the wheels are same brand

3) Drive to tyre center and change the bulged tyre straight (spare remain as spare, not touching).

Of all 3 options, which one do you think is the better, safer option i should do? Not sure if just changing 1 front tyre is advisable? I checked the condition and thread of the other good tyre and it is still in good condition (can use maybe another 2 years?) Quite a noob in car so really appreciate the help of all the sifus here.

if you're not on tight budget, option no.3 is the most viable.

if the spare is the same size, then get 1 new tyre to replace the bulged tyre.

swap the spare with the front left tyre and keep the front left tyre as spare

u can replace ur bulge tyre with ur space and get a 2nd hand tyre as spare. Provided ur spare and replacement 2nd hand tyre is in good condition.

Id do option 2

go option 1. use until time to change all 4 tyres but keep 1 as the spare n throw the bulge one away.

Thanks for the advise all. Seems like everyone has different opinion of what to do with the situation haha.

I actually never thought of this and it is actually a pretty good idea! Now both front tyres are new and can be changed at the same time when their thread runs out together.

Factory Proxes R50? My Yaris' R50 also got a bulge on the side wall few months ago and went for option 2 as the spare is the same size, but i did not keep the bulge tyre. Now saving monies to change all 4 tyres, then keep 1 of the 4 as spare

Didnt you already swap with the spare? Why do you need a new spare tyre? Im pretty sure you can drive 10-20KM if you ever need to swap with the bulge tyre again and find a tyre shop.

I would just go on with it and wait until I need to change tyres again. Then swap all 5 with brand new.

A buldge on the side of the tire means that there is a tear in the nylon ply of the carcass. Structurally the tire has a weak point and could fail while driving. I would recommend to change to the spare tire before driving further.

The buldged tire must be replaced.

You could do option 2. But i would recommend to rotate your tires a bit more frequently just to balance out the wear overall since your spare would have more tread compared to the other 3 tires.
