Thread: Want 35" engineered on my d2 what to look out for

A lift is only part of a solution and doesn't allow larger tyres on its own. A lift changes static height only...

Bump stop changes etc are required to fit larger rubber - not big springs on their own!

very true

But as Tombi mentioned lift itself is just one component, I had to further massage my inner guards, progressive bump stops etc...

It would be interesting to see the EGT uphill with those huge tyres though

Gearing and tune should mean no significant difference...

My own vehicle contradicts that unfortunately cos all i did was to fit bigger tyres and the EGT and consumption had a noticeable increasement then thinking it was coincidental with some management issue swapped back to std dimensions and everything dropped back to normal, fitted the bigger ones and the EGT rose again... so did the breaking distance too

Gearing I did type gearing in my post...

In my limited mind "gearing" is linked to tyre size too, so is "tune"

i used this calculator https://tiresize.com/gear-ratio-calculator/ and compared the D2's std sizes for 16" wheels(255/65/16; 235/70/16) with close to 35" tyres(315/77/16) to see the proper gear ratio for each and the results are impressive so if only bigger tyres are fitted without ratio mods that higher EGT thing is logical IMO

Perhaps I need to add more words..

The vehicle you made the comment about has had Gearing changes (ratios) and tuning altered..

(And I do tyre size calcs in my head btw, done it for decades)

So it has the correct mechanical advantage to keep loads down...
