Onyenna: 235-50-18 and 245-50-18 will have same height..the only difference is the width(ie 235 & 245)...255-40-18 will still be of same height but shorter-stomach-area(by the side) and it will probably have the largest width compared to 235 and 245...they all have a difference of 10(width-wise) ie 235,245 and 255...... Summary: they all have same height which means your car is Balanced..... You're not in any Danger sir.....

cmpunk: I need advice too. i have an Honda bullet(tiger face)
that came with 185 65 14 tyre. I upgraded all the
four to 195 70 14 tyre. Any pros and cons? sienna
and co over to u. pls what's d standard tyre
measurement .

a beg l need answers sienna and co.

abatically:

I doubt siena knows what is Honda bullet

MD-CEO:

Meanwhile, i checked the car user manual i downloaded online, and found that the recommended tyre size was 205-65-R16.

Is there any immediate danger in driving them as they are now?
I'm asking because I'm really hard pressed for cash this Christmas season with so many other things to do simultaneously. I'll prefer deferring changing all 4 tires till sometime in January when there'll be more cash liquidity for me.
For now, i can only really afford to buy one tyre to replace the single one that went bad.
What size should i buy now with the multiple sizes I already have on the other 3 tires.
What do you advise?

DECOtech: Find a 205-50-18 for the four wheels.

timbros:

How do I calculate me MPG please? It seems my '96 Camry is guzzling fuel too much now more than before.

Help needed asap please.

hmiso:
Xtreme Fuel teatment is the solution. with XFT u re sure of sound engine, fuel cost friendly and less visititation of ur mechanic

Siena:

I'd love to know where he'll get a 205/50x18. Never seen one, not listed on any tyre website. Doesn't meant they don't exist though, but must be rare as hen's teeth.

MD-CEO:

Abi is there any other issue with using bigger tyres than recommended, other than fuel consumption? (provided the 4 tyres are all the same size, or at least, the same size on each axle).

MD-CEO:
I just got a registered Nissan Altima 2003 a few days ago.

To my amazement, i found that all the other 3 remaining tyres had different sizes.
The sizes are-
235-50-18
245-50-18
255-40-18.

Is there any immediate danger in driving them as they are now?

Ikenna351:

Aside fuel consumption, you should forget about the speedometer, because it's going to be useless. It will simply throw off the speedo. Imagine doing 80km/h, while your speedo is reading 120km/h or so. It's just like swapping in an Inline-4 Tachometer in a V6 Car. The V6 engine will simply throw off the tacho. That is, if your actual rpm at idle is 750 rpm, the I4 tacho in V6 car will be reading 1,500 rpm or even more.

Since you said the car left the show room with 205/65 R16, I wouldn't go beyond 205/60 R17 or 205/55 R17, if I were you.

In one of the trips i have done in my Baby, i had a blowout (long story), along Enugu-Onitsha Expressway. I got to Enugu and searched for the same size of the damaged tyre (195/60 R15), since the 4 tyres were the same size, including the spare. Unfortunately, I couldnt find 195/60 in Coal Camp, rather, 195/65. Why? Because there was more demand of high profile tyres in the East, considering the nature of the roads down there. Because i would be driving back to Abuja the next day, I had to buy the 65 available, instead of 60, since i didnt have the time to go round the town in search of the size 60. I mounted the tyre that same evening. The next day, on my way back to Abuja, It was a nightmare. Every hard braking or sharp steered of the wheel, the car would try to veer off the road. It was as if it was a different car. Did i enjoy the drive? Not even for a second. . I got to Abuja and replaced it with size 60, since low profile tyres are very much available here in Abuja. Thanks to Abuja road!

Just 1 different size tyre messed up the car stability on highspeed. In my case, it was horrible. In your case, with the 3 different sizes you listed, it will be something else.

Maybe because i don't speed though, and I don't attempt to pull any James Bond stunts...

Siena:

The factory size tyres for a 2005 Honda Accord (with 16" wheels) is actually 205/55x16 or 215/55x16. Earlier cars with 15" wheels had 195/65x15 or 205/60x15.

The size you're running right now is a bit on the large side, but the effect on fuel consumption will be negligible. I would be in a rush to buy new tyres. Use them until they wear out, then replace with 205's.

Siena:

You asked for advice,which is what you got. Your comment here makes you come across as smug and conceited. I'm not saying you are, just that's the way I read it.

Ok @Kenyarttar, but i didnt really understand your post. Were you asking a question, or giving a testimony, or thanking all the experts on the thread.........or all of the above?
