giddyup Posted October 6, 2015 Share Posted October 6, 2015 I asked in a previous post about trading in my alloys on something a bit different, now I have a different question. My existing alloy wheels are 16" with 245/70R/16 tyres. If I wanted to put say 18" wheels on the pickup, what size tyres would I need to keep the same circumference and therefore not affect speedo, transmission etc? Obviously the tyre would need to be a lower profile, but is there any kind of formula for working this out? Link to comment Share on other sites More sharing options...
JAS21 Posted October 6, 2015 Share Posted October 6, 2015 (edited) Here is the calculation http://www.etyres.co.uk/how-to-change-your-tyre-size/ for the understanding. Hopefully someone will say what hey have fitted. My experience is that they don't worry too much about the overall diameter as long as the tyres don't rub on the bodywork. It looks like a 60 section.

giddyup Posted October 7, 2015 Author Share Posted October 7, 2015 Is there anything to stop me putting regular road tyres on a pickup as opposed to the truck style tyres already on there? Link to comment Share on other sites More sharing options...

Cheers. Looks like I need a 245/60/18 to keep almost the same circumference. Most people, when going to the expense of changes their wheel size to increase diameter they also buy wheels that are wider to accommodate a wider tyre. This is the main reason that the wheel size change is made, in order to have wider tyres that give a fuller look with more tyre surface touching the road. In your case, if you were to increase the wheels to 18inch then to keep the same overall diameter as your original, you would need to fit 265/55/18 tyres. Please Note: Your new wheels would need to be 10.5inch wide to fit the 265mm width tyre. Edited October 7, 2015 by sotsira Link to comment Share on other sites More sharing options...
JAS21 Posted October 7, 2015 Share Posted October 7, 2015 (edited) Giddy ... I suggest that you have a look at www.tuneruniversity.com A huge amount of information on wheel and tyre sizes and effect on handling etc 20 inch wheels seem to look good on many pickups. Your gps will give you an accurate speed The whole site is well worth a read ... Edited October 7, 2015 by JAS21 Link to comment Share on other sites More sharing options...
sotsira Posted October 7, 2015 Share Posted October 7, 2015 (edited) Your last sentence....High end Vigos have 265 tyres, think rims are 8 inch.. My fun ride had 265/50 on 8.5 inch and 325/50 on 10 inch. There's a fair amount of tolerance when choosing the rim width with tyre width size. EG: An 8inch rim can accommodate from 215mm to 245mm wide tyres. A 10inch rim can accommodate from 255mm to 285mm wide tyres. The key is to fit the closest matching rim in inches to the equivalent size in mm so as to keep the side walls as square as possible. If you choose too much over or under tolerance the side walls of the tyre either bulge or stretch too much which then affects tyre performance, especially on cornering ability.

sotsira Posted October 7, 2015 Share Posted October 7, 2015 This is going to be interesting ... hopefully we will all learn something ...lets go guys Firstly i'm not here to get in to any arguments but i'll try and explain my advice. What T/A is saying could well be true but that does't mean it's the ideal correct sizes to use when your buying new rims and tyres. The rim width used on factory stock vehicles are always the min required to save on manufacturing costs. The problem there is that the tyres will fit, but bulge on the sidewalls. If you want to get the best performance from the tyre width, the rim width needs to be the same or 1/2 inch narrower,this would allow the whole tyre width to stay in contact with the road surface when under cornering load. Here is a website that i've found to back the dimensions i previously stated in this thread. http://www.tyresizecalculator.com/tyre-wheel-calculators/tyre-size-for-rim-size-width-calculator Link to comment Share on other sites More sharing options...
Ace of Pop Posted October 7, 2015 Share Posted October 7, 2015 Increase Width, increase Aquaplane. Link to comment Share on other sites More sharing options...
DavisH Posted October 8, 2015 Share Posted October 8, 2015 (edited) Increase Width, increase Aquaplane. Up to a point, but that will be more exacerbated when the tread depth gets low. My dad had a ford fairlane with 265 on the rear, when the tread got low it was all over the place in the wet. But on my swift the 205 pilot sports (wide deep grooves) feel much more secure in the wet than the stock 185's (skinny grooves). I don't think there would be much difference from going from 245 to 265, as long as the tyres are of good quality.

pgrahmm Posted October 8, 2015 Share Posted October 8, 2015 (edited) Make sure you have the correct offset + plus no clearance problems over expected and unexpected bump/ruts/potholes......Both unladen and laden...... We just got back from a road trip....there were some potholes with about a 6-9" depth - I was glad for the fact I didn't have low profile tires.....I'd have been left sitting in the middle of nowhere.....

I have the car and I know what size wheels it came with because I wanted to swap the Michelins off my old truck over (8"), but the new wheels were wider (8.5").

Ace of Pop Posted October 11, 2015 Share Posted October 11, 2015 The Mazda 3 is the only Car ive seen here with descent O.E,wheels for a while. When U look at one U dont think Must Change them like most other brands.Ford n Toyo have been whacked with a "Fugly Club ". The big Swift wheels dont look like an Accountants Choice either, nice balance there too imo.. Link to comment Share on other sites More sharing options...
